Wonderful idea, needed simplification, but it doesn't work with Tbird 78.7.1. If I hide an icon on the Quick Filter Bar, and then close the bar with the Quick Filter icon, I can't get it back with the icon or the keyboard. Restarting Tbird doesn't help. Please fix it so I can change to 5 stars.

It will be fixed in v2.1.1, which is now waiting for approval by a reviewer.
Sorry for the late answer.
