Highlight filter matches in list of backends

[christophfriedrich]

Currently, changing filters on the right hand side of the Discover section causes appearing/disappearing of backend entries on the left hand side - and that's it. So when the user wants more information on the things he actually matched, he has to search manually through the information on the left hand side.

Some ideas:

• highlighting keywords (e.g. user searches for "sentinel" in Collections input -> all occurrences of the word "sentinel" are displayed with yellow background)
• matched items could be sorted at the top (and the rest either or <hidden and expandable with a "show all" option>)
• matched parts could be expanded automatically
  • reasonable?
  • To avoid increasing the prominence of the first backend too much, the backends themselves should remain collapsed (only their content expanded automatically according to filter result)
  • How to deal with situation where the user has filtered, closed some auto-opened parts, then changes filters -> overwrite user decision?
