still a feature that i like in Firefox is that the toolbar shrinks it self when going into fullscreen.
that would be cool to have it in k-meleon.. more than that i suggest that the fullscreen toolbar could be customized sepparately from the normal view toolbar.
for example i would like to see in fullscreen view only the address bar cuz i use mouse gestures and i dont need other buttons.
hope u get my point.

Edit-Adv.Prefs-GUI Appearance has some fullscreen options. "Hide Task Bar" doesn't work properly though.

are still a few fullscreen options... will we see more fullscreen options in the new release? we'll see!
