disabling buttons == very bad choice Rated 5 out of 5 stars
well, as I see in the forums, it appears that some user complained that he must disable the extension when he changes the theme, and the author complied;
need I say I don't agree with this move at all? I was using it together with the iPox theme and "hide menubar" extension to gain some more space on my eeepc's screen while maintaining a decently looking browser (I may be not the only one that thinks the "Chrome look" sucks)
So, yeah, please open it up again! or make hiding the buttons when using other themes an option (enabled by default, to cater to idi^Wlazy users).
