## Development

For development use:

```
$ npm install (in case of an error, run `npm install --legacy-peer-deps`)
$ npm start
```

Also you can test it locally using Storybook:

```
$ npm run storybook
```

## Future plans

- Test coverage
- ~~Programmatic access to the editor input as JSON~~
- ~~Localization~~
- Ready templates with different options (MUI, Bootstrap, etc...)
- Dark/Light modes
- Custom styling flexibility
- ~~Disassembling all of the toolbar to enable using them as nested components, increasing the flexibility~~
- ~~Enabling adjusting editor settings such read-only mode and etc. programmatically~~
