Canvas and sidebar interaction polish tracking issue

[SaxonF]

What problem does this address?

Using the editor / interacting with the canvas should feel intuitive. This requires a level of polish, particularly surrounding microinteractions, that we currently don't have. There are expected interactions that either don't exist (e.g. infer layout via drop position) , don't work as expected, or buggy.

This is a tracking issue that highlights opportunities for improvement with the ultimate goal to create a polished editing experience that is enjoyable to use.

Prioritised tasks, aiming for WP 6.5

• Drag & drop overarching issue: Block drag and drop tracking issue #33683
• List view drag and drop: Make it more obvious blocks can be dragged: List view drag and drop: Make it more obvious blocks can be dragged #33686
• List View: Right click on items to expose settings: List View: Allow right-click to open block settings dropdown, add editor setting #50273

Needs design and/or more info and a separate issue to be created

• Expose drag & drop: Expose before/after in drag and drop experience #54952
• Transforms: should expose variations for things that have them in a fly out menu.
• Consider removing the toolbar handle
• The chip when drag&dropping in the list view is too big
• Multi-selection down works, but not when you move the mouse up
• Selecting multiple blocks in canvas that span multiple levels
• On canvas controls for padding and gap

Long-term (not yet prioritised for a particular release)

• Press Esc to hide block outlines and block toolbar, press Esc again to enter select mode #59646
• Image resize handles: When dragging the resize handles, snap to wide / full widths #44357

I've done a little re-ordering of this issue to add a section for issues that are prioritised for 6.5 and are ready to be worked on (or are already in progress), with other issues moved to a section flagging that new issues need to be created, or where design work is needed before development can commence.

Feel free to update and edit the description as needed!

Tiny update: the List View right click PR has been merged. I've opened up a follow-up issue in #57091 to discuss ideas for other areas in Gutenberg where a custom right-click contextual menu could be useful. There's likely lots to consider if expanding it to the editor canvas, so hopefully that issue will be a good place to tease out the ideas or designs if and when it's to be explored.
