On the computer I am currently using the resolution is 1024×600. The width is ok, but the height really requires applications to “behave”. I am using GNOME (since early 2000 something) and Thunderbird. I dare not switch to other softwares since I fear the wrath of Andreas Nilsson (GNOME, Mozilla).
Anyhow, since GNOME is stealing a lot of pixels from me (panels) and Thunderbird does a good job at stealing pixels too I could really do with a full screen mode.
So please Thunderbird developers, Andreas in particular, gimme a full screen mode for Thunderbird.
