Editable Strategy

[ellatrix]

This is more of a discussion ticket, with some points on how I see Editable going forward, so we can discuss and get on the same page.

1. Implement multi selection: Multiple block selection #62 + Add multi select #896.
2. Once we have multi selection, we might be able to return to one paragraph per text block:
   • This could make Editable much simpler as we can remove the non inline version. There would be only one state structure.
   • Blocks like lists and quotes could be created from multi selection. We can have a toolbar for commands that are possible on multiple selected text blocks.
   • There's no need to "normalise" paragraphs and merge/split them to transform to a list/quote/etc.
   • Alignment is truly per block.
   • Line break on enter becomes easy (though we don't have to do it).
3. Editable state as string + meta data: RichText State Structure #771 + Experimental Editable state #847.
   • This also becomes much simple because we only need to handle the inline case.
   • Enter/backspace behaviour should be easy to adjust.
   • More benefits: RichText State Structure #771 (comment)
4. Add text shortcuts. With just a string as the Editable state, it's easier to make transformations to other blocks (code, hr, heading), or add extra meta data (like formatting).

Closing as multi-selection is done and editable state is being discussed elsewhere.
