Edition
GNOME 2, continued. Traditional, light, and endlessly rearrangeable.
MATE is a maintained fork of GNOME 2, with Marco handling windows. Mint ships it with a single bottom panel, much like Cinnamon — but the classic two-panel layout, menus along the top and a task list along the bottom, is a few clicks away.
Lighter than Cinnamon, heavier than Xfce, and the most willing of the three to be rebuilt into whatever shape you had in mind.
