The Window Picker Applet is an GNOME applet (developed at Canonical) that displays the list of running applications and allows you to switch between them. It’s a default applet in Ubuntu-netbook-remix, since on netbooks the screen real estate is essential.
It’s a nice little applet, but unfortunately does not work well with vertical panels, since it tries to display the icon list of the running applications horizontally (see this bug). I’ve developed a patch to window-picker-applet-0.4.22 that solves this issue.
To use it, do as follows:
apt-get source window-picker-applet cd window-picker-applet-0.4.22 patch -p1 < $PATH_TO_THE_PATCH_FILE |
and then the usual:
./configure cd src && make && sudo make install killall gnome-panel |
Note that this patch *needs* gnome-panel to be restarted, since the panel orientation is chosen at initialization (I’ve not implemented yet the orientation change during execution).
