Keyboard Navigation

Make texts easier to read (more opaque background?)
Only show tooltip when text is truncated
Hide "highlight" frame when cursor is not over any item
When search results are incrementally added, opacity of all existing result items goes to 0 and back to 1

After entering a category there is no obvious way to go back, add a "Back" button or breadcrumbs?
Clicking a folder from the "Files" runner opens the folder in Dolphin, it should list the folder content IMO, just like one can enter a category
Tabs on the top seems to be hardcoded, should they be customizable or at least extensible?
Typing a search term in the search box searches in all runners by default, instead of the current one
Favorites should save to the config. Currently having issues getting it to save _anything_.

What is the difference between "Categories" and "Apps"?
