I just gave one of your extensions 1 star review, so here: this is what I've wanted for since AIO Sidebar went away with legacy extensions. I think it was the one that could show all the about: pages.

Does it have all of them? What about possible other similar stuff - I know there are some other URI beginnings, but don't know if their useful for this (like view-source:). But there might be more I don't know about.

Anyway, excellent!
