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 result items which are already there should not change. Right now 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*.
Hide the salviewer popup when an executable/item is launched. That would require some kind of signal from the qml side, connected from the C++ applet side, which would then send a dbus command. A cleaner route would be nice, but I believe that's the only way.
Create a "Close" button rendered on top of sal. That code would have to be written *inside* salviewer itself.
Install sal-qml as not only an applet, but a containment as well. So as to replace the current broken C++ one in master.

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