[TODO this is so far just a quick task to have the information here.]

This task is mostly for the ID-template, but some of the design changes might work for regular search menus with data-blocks selected too.

• We need an easily discoverable way execute operations on data-blocks, like "Make Local", "Add Library Override", "Delete Override", etc.
• Could we show the library status (linked, overriden, missing), library name and user count info in or next to the search button, so users don't have to open the menu?
• How to deal with cases where there's little space, like in more space-saving regions?
  

In 2.90 there were a couple of visual tweaks already, to make data-block management in production scenes simpler for search menus:

This design takes more space, so there are issues like T77929.
