The Sezen Applet is finally ready for Ubuntu Maverick! This wasn't possible until now due to a bug, but you can now install the Sezen GNOME panel applet from our Unstable / Unreleased / Backports PPA.
Sezen Applet is the integration of Sezen - the new Unity like activity browser which uses Zeitgeist to browse files based on their last access time -, into the GNOME panel.
To install the Sezen Applet in Ubuntu, use the following commands:
sudo add-apt-repository ppa:webupd8team/unstable
sudo apt-get update
sudo apt-get dist-upgrade
Or you can manually upgrade the gnome-applets and gnome-applets-data packages.Then you can simply right click the GNOME panel, select "Add" and then add "Sezen". If you get an error the first time you add it to the panel, remove it and add it again and it should work just fine.
The Sezen Applet was the last (I think) package we maintain in the WebUpd8 PPAs (here is a list with all the PPAs we maintain) which was not ready for Ubuntu 10.10 and is not in the Maverick repositories already.
