Manage Reusable blocks without leaving Gutenberg

[paaljoachim]

Bringing the Manage Reusable Block into the Gutenberg screen.
Looking at the current method there is a manage reusable block link in the Inserter panel.

Here is an example of the Reusable block inserter panel:

Clicking Manage all reusable blocks
exits the Gutenberg screen, and goes here

It would be a lot more helpful to have editing happen inside the Gutenberg screen. Making it possible to turn on and off managing Reusable blocks. The design suggestion I made still keeps it associated with the Inserter panel. It would be very helpful to keep the association in place. Keeping managing reusable blocks close to where we already insert the block into the layout.

Clicking Manage all reusable blocks
Could instead just show the Edit l Trash l Export links like so

Opening it up directly in the same Reusable inserter panel.

Here is a prototype that I made in figma.

Here is one way to handle trashing a reusable block. Draft would also be added here.
Look at the flow. The placement of the All l Published l Trash options are likely not ideal. This though gives an idea of what it might look like.

Here is another animated gif.

Next version. This time with an overlay.
An overlay can be used to show Reusable blocks, patterns, template parts, template sections etc in a bigger area.
User clicks either the manage link or the expand icon to open the Overlay.

Clicking the checkbox next to an item will show the options Edit l Trash l Export below.

I am just adding the below here as this is a very interesting feature.
This plugin adds a way to convert reusable blocks into patterns: https://wordpress.org/plugins/reusable-blocks-extended/

Here is a pattern modul/overlay suggestion which is very much associated to this Reusable blocks modul issue: #26905

Related to this is that one cannot remove a reusable block from the trash from within the editor.
