We should keep consistent with the use of curly brackets for `if` clauses; CS says for them we shouldn't use them for single line statements, so this should be

```js
if (options.isInSidebar)
  this.isInSidebar = options.isInSidebar;
```

Also this could be rewritten as

```js
this.isInSidebar = !!options.isInSidebar;
```
