In guake, if I press "F12", I get the semi-transparent HUD-like terminal as expected. But if I then press "ctrl-shift-t" to open another tab, the new tab will not be transparent any more. Is this a bug or a feature?
yes definitely its a bug. i just removed and installed it again and now its working fine. after installing it again, when you open it for the first time, the first window completely opaque. its nothing. just go to the preferences>>appearance tab and then re-adjust the transparency option scroll bar to some other value. thats it. its done.
hope it works.
