The entire interface is divided into four categories - Overview, Tweaks, Admins and Janitor. Plugins can be installed for all of these categories, though in this release they are available for Overview category only.
- New UI
- New clips feature : system and other information
- All features are plug-able
- Package Cleaner becomes a new major part as the “Janitor”
You can install beta version from Ubuntu Tweak PPA. Both Natty and Oneiric packages are available but in my testing many features did not work on Oneiric. Also Ubuntu Tweak detected Gnome 2 on Oneiric and not Gnome 3 so it is probably more useful on Natty at this time.
To add the PPA and install Ubuntu Tweak, run the following commands:
sudo add-apt-repository ppa:tualatrix/next
sudo apt-get update
sudo apt-get install ubuntu-tweak
Ubuntu Tweak 0.6 beta is currently missing Application and Source Center. These features will be added in future but If you want these features, you can install Ubuntu Tweak 0.5x by running the following command:
sudo apt-get install ubuntu-tweak-0
Remember that since it is a beta release, there will be bugs. You can also help by writing new plugins for Ubuntu Tweak. More information can be found on links below:
