Currently the interface essentially forces one to use modifier keys to access most of its functionality, whether that is playing/pausing, adding to the queue, or switching tabs. Interestingly enough, if you bind those functions to single keys, the operations still work, but you can no longer type in a search box.

Ideally this would be toggleable functionality, so if someone binds search to a shortcut (say "s"), then they can use any combination of keys to access other systems, and still be able to type in the search field when "s" is pressed.
