This is darn near exact what I have been looking for since upgrading to Quantum. So far my biggest critique would be that when the bar is open certain webpages that have static objects at the bottom of the screen become covered by it. Seems the bar is more of an overlay than integrated in the actual body of the browser, I dont know if this is because of the WebExtension protocol but it would be helpful to have the option to shrink to mini-mode or hide the bar to access these types of items. Thanks for your hard work and I look forward to seeing this extension evolve.
