when i press backspace (to delete a task), akiflow runs into an error and needs to restart when this script is injected, can u figure out why that might be?
Assistant: Thanks for providing the script!

From what you described, the crash/restart happens **when pressing backspace to delete a task** while this script is injected. That suggests the script interacts with DOM nodes that might be removed or manipulated during the deletion, and some code might not handle those state changes gracefully.

Here are some likely reasons and points of failure in your script:

### 1. DOM Elements Might Become Null/Detached

If the user presses backspace to delete a task, the `.planner-task` element or its children might be removed from the DOM. Your code assumes the queried elements exist, but if they are removed during iteration or immediately afterward, operations on them might throw errors:

- In particular, these lines:
  ```js
  iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
  ```
  - If `iconContainer.parentNode` is null or `durationHolder` is null, this will throw.

- Also:
  ```js
  const nestedTitleSpan = taskTitleSpan.querySelector('span');
  ```
  - `taskTitleSpan` could exist but `querySelector` could return null, so you guard here looks good.

- The overall issue is when the task card itself is deleted midway while your code runs or after your code modifies it.

### 2. Mutation / Event Timing Conflicts

Your function `fixStyling` is applying an effect on all `.planner-task` elements. If the deletion action triggers DOM mutations (removing `.planner-task`), and your code is attached to some events or reactively called, race conditions might cause invalid DOM references.

---

### How to troubleshoot / improve robustness

1. **Add null checks and fail-safes** at every point you access or manipulate elements that might be removed:

  For example, before:
  ```js
  iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
  ```
  Ensure:
  ```js
  if (iconContainer && iconContainer.parentNode && durationHolder) {
    iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
  }
  ```

2. **Wrap risky DOM operations in try-catch** blocks to prevent uncaught exceptions from crashing the app:

  Example:
  ```js
  try {
    if (iconContainer && iconContainer.parentNode && durationHolder) {
      iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
    }
  } catch(e) {
    console.warn('Failed to move durationHolder:', e);
  }
  ```

3. **Avoid direct manipulation of the DOM on nodes that might be deleted soon**

   If deletion is triggered in the UI, you might want to debounce or delay this script execution, or better: listen to DOM mutation events or app-specific events and only update styles on existing nodes.

4. **Monitor errors in browser console**

   Replicate the crash and check the browser console for exact error messages and stack traces to pinpoint the faulty line.

---

### Additional detailed review of potential crash spots

- `iconContainer.parentNode.insertBefore(durationHolder, iconContainer);`  
  If either `iconContainer`, `iconContainer.parentNode`, or `durationHolder` is null or the node is already detached, this throws.

- In the event listener `handleColorSchemeChange`, the code calls:
  ```js
  document.querySelectorAll('.planner-task').forEach(applyDynamicStyles);
  ```
  If some `.planner-task` elements are partially removed, their internal elements might be missing.

- The `applyDynamicStyles` function accesses `taskCard.classList` and `taskCard.style` assuming `taskCard` is not null.

---

### Suggested minimal fixes to reduce the risk of errors:

Update `fixStyling` to include safe guards:

```js
const fixStyling = () => {
  const lightModeStyles = { /* ... */ };
  const darkModeStyles = { /* ... */ };
  const consistentStyles = { /* ... */ };

  function applyDynamicStyles(taskCard) {
    if (!taskCard) return; 
    const prefersDarkMode = window.matchMedia('(prefers-color-scheme: dark)').matches;
    const modeStyles = prefersDarkMode ? darkModeStyles : lightModeStyles;
    const fancyBorderClass = 'dailyGoal';
    const hasFancyBorder = taskCard.classList.contains(fancyBorderClass);

    for (const property in consistentStyles) {
      if (consistentStyles.hasOwnProperty(property)) {
        taskCard.style.setProperty(property, consistentStyles[property], 'important');
      }
    }

    if (!hasFancyBorder) {
      taskCard.style.setProperty('border', modeStyles.border, 'important');
      taskCard.style.setProperty('box-shadow', modeStyles['box-shadow'], 'important');
    } else {
      taskCard.style.removeProperty('border');
      taskCard.style.removeProperty('box-shadow');
    }
  }

  function handleColorSchemeChange(event) {
    document.querySelectorAll('.planner-task').forEach(applyDynamicStyles);
  }

  const taskCards = document.querySelectorAll('.planner-task');

  taskCards.forEach(taskCard => {
    if (!taskCard) return;

    try {
      taskCard.style.flexDirection = 'column';

      const iconContainer = taskCard.querySelector('.flex.items-center.justify-center.gap-px');
      if (iconContainer) {
        const durationHolder = iconContainer.querySelector('.h-5.relative.flex.items-center.justify-start.px-1.bg-grey-100.border.border-solid.border-white.hover\\:bg-grey-300.rounded-md.cursor-pointer');

        if (durationHolder && iconContainer.parentNode) {
          iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
        }

        taskCard.appendChild(iconContainer);
        iconContainer.style.marginLeft = 'auto';
        iconContainer.style.paddingTop = '5px';
        iconContainer.style.marginRight = '0';
      }

      // Remove max height limitations
      taskCard.style.setProperty('max-height', 'none', 'important');
      taskCard.classList.remove('max-h-[54px]');

      // Improve layout of title span
      const taskTitleSpan = taskCard.querySelector('span.text-2xl.font-medium.text-grey-900.font-sans');
      if (taskTitleSpan) {
        taskTitleSpan.style.display = 'flex';

        const nestedTitleSpan = taskTitleSpan.querySelector('span');
        if (nestedTitleSpan) {
          nestedTitleSpan.style.wordBreak = 'normal';
          nestedTitleSpan.style.overflowWrap = 'break-word';
          nestedTitleSpan.style.whiteSpace = 'normal';
        }
      }

      // Remove h-5 from task header
      const taskHeader = taskCard.querySelector('.planner-task-header');
      if (taskHeader) {
        taskHeader.classList.remove('h-5');
      }

      // Remove h-5 from icons in icon container
      if (iconContainer) {
        const iconElementsWithH5 = iconContainer.querySelectorAll('.h-5');
        iconElementsWithH5.forEach(iconElement => {
          iconElement.classList.remove('h-5');
        });
      }

      // Apply mode-based styling
      applyDynamicStyles(taskCard);

    } catch (e) {
      console.warn('Error styling task card:', e);
    }
  });

  const colorSchemeMediaQuery = window.matchMedia('(prefers-color-scheme: dark)');
  colorSchemeMediaQuery.addEventListener('change', handleColorSchemeChange);
  window.addEventListener('beforeunload', () => {
    colorSchemeMediaQuery.removeEventListener('change', handleColorSchemeChange);
  });
};
```

### Summary

- Wrap DOM manipulation logic in `try-catch`.
- Always check if a node or its parent exists.
- Avoid assuming the node is attached — e.g., check `iconContainer && iconContainer.parentNode`.
- Add logging to locate exactly where it fails.
- Confirm what triggers the backspace event and interception; ensure this function isn't called at an invalid time on disconnected nodes.

If you apply these changes and the app still crashes, it would be helpful to get error details from your browser console.

If you want, I can help you further debug if you can share the error log or how the deletion works internally in Akif
User: still caused the crash
Assistant: If adding guards and try-catch did not stop the crash, then the cause is likely related to **your script running while the DOM is in an unstable state during deletion**, or **some operation attempts to insert or manipulate nodes that are removed or being removed**, causing an uncaught error inside Akiflow's own internal code (which you can’t control).

### Possible root causes beyond your script syntax

1. **Manipulating DOM nodes that Akiflow is simultaneously modifying or deleting**  
   For example, your script moves nodes around (`insertBefore`, `appendChild`) — if Akiflow’s deletion logic is partially complete during this, it may cause race conditions or trigger invalid internal state, leading to a crash.

2. **Mutation side effects triggering unexpected reflows or event handlers**  
   Your changes might cause unexpected side-effects in Akiflow’s event handling or internal state, which then crash.

---

### Recommended next steps to fix or mitigate this:

#### 1. **Throttle / debounce your script to run _after_ deletion finishes**

If your code is run synchronously on every keypress or backspace event, try instead to detect deletions and then run your `fixStyling` **only after a short delay** (to let DOM stabilize).

Example with debounce:

```js
let debounceTimeout = null;

const debouncedFixStyling = () => {
  clearTimeout(debounceTimeout);
  debounceTimeout = setTimeout(() => {
    fixStyling();
  }, 100); // Wait 100ms after last call to run fixStyling
};

// Instead of running fixStyling directly on UI change event, call debouncedFixStyling()
```

You can hook `debouncedFixStyling()` to appropriate events (e.g., mutation observers, Akiflow’s own event hooks) or tie it to a `setInterval` so it runs periodically rather than on every mutation immediately.

---

#### 2. **Use a MutationObserver to wait for stable DOM**

Instead of manually running `fixStyling` immediately, observe the `.planner-task` container and only apply styles when tasks are fully inserted or changed:

```js
const container = document.querySelector('.planner-tasks-container'); // Adjust selector

if (container) {
  const observer = new MutationObserver((mutations) => {
    // Whenever the task list changes, debounce applying styles
    debouncedFixStyling();
  });
  
  observer.observe(container, { childList: true, subtree: true });
  
  // Call initially too
  fixStyling();
}
```

This way you react to changes, but only after DOM finishes mutating.

---

#### 3. **Avoid moving DOM elements in place if possible**

Your code moves `.h-5.relative.flex.items-center...` elements out of their container —

Example:

```js
iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
```

This directly mutates the structure and can conflict with Akiflow's management of these nodes during deletion.  

**Try instead only applying CSS styling without moving nodes** to see if that fixes the crash.

---

#### 4. **Catch errors globally and log**

Add a global error handler to capture more info:

```js
window.addEventListener('error', event => {
  console.error('Global error captured:', event.message, event.error?.stack);
});
```

This may tell you exactly which operation or stack trace crashes Akiflow.

---

#### 5. **Verify your code is not triggering infinite loops**

- Styling changes triggering mutation events
- Mutation observer firing repeatedly causing continuous DOM changes  
If this happens, it might destabilize Akiflow or cause performance issues leading to a crash.

---

### TL;DR

- Wrap all DOM manipulation in guards & try/catch (you already did).
- Avoid moving nodes; only style them.
- Use `MutationObserver` & debounce `fixStyling` to run after deletion completes.
- Add global error handlers for more diagnostic info.
- Ensure no infinite loops happen from mutation + handling.

If you want, I can help you rewrite the core parts avoiding node moves and focus only on styling, and provide a very safe version of your script.
