Brilliant add-on, love it! Option to hide from side bar would be good, I don't use it, nevertheless👍🏻

Bug: if you enable "synchronize settings" on a *new* webbrowser/profile, it uploads these default settings, and "deletes" your original/previously synchronized settings on all other devices...

I also love that i can "zap" sections with uBlockOrigin and then save the result <3
