I like extensions that do one thing and do it well. No clutter here!
Unfortunately the keyboard shortcuts break wordwise cursor movements in text fields (Ctrl+left/right). The handlers should at least not block the default handling if keyboard shortcuts are disabled in the extension pop-up. Ideally the extension would detect a text field being focused.
Some suggestions:
* Add tooltips to the buttons in the pop-up.
* Particularly for using Flow, add buttons for adding/removing favourites (ideally with a visual indicator of whether the song is currently favourited) and for disliking songs. With keyboard shortcuts, ideally.
Anyway, thanks for this nice extension, and it would be lovely if you could change the shortcut handling!
