This is the stable release, so we support all of GNOME Shell
stable cycle without updates.
(As said earlier, dock and alternate-tab have issues, so they're
not marked 3.2 but just 3.2.0)
Now it is possible to use GSettings to configure the placement
strategy (natural KDE-like or default grid) and whether to consolidate
the windows more tigthly, as well as the position of the window
captions.
This extension employs an algorithm (taken from KDE) for layouting
the thumbnails in the overview that more closely reflects the positions
and relative sizes of the actual windows, instead of using a fixed
grid.
