A new Ubuntu Tweak Beta has been released and it comes with some really nice features.
Ubuntu Tweak is a tweaking utility which provides a frontend for tweaking many system settings that would otherwise be possible through terminal commands or gconf editor. It also features a nice application and a sources (ppa) manager.
Reset buttons. If you change some settings and want to go back to defaults, its easy.
Backup and restore facility for desktop, applications and system settings:
I think this feature may be similar to upcoming OneConf in Maverick that can make a backup of applications list, some application settings and some application states and sync them with Ubuntu One Database and other systems. If Ubuntu Tweak can sync these backups with some services like Dropbox or Ubuntu One itself it will be really nice (though these new features are awesome as it is).
Note: This is a beta version (0.5.6) and there will be bugs. So beware.
To install, execute following commands in terminal:
sudo add-apt-repository ppa:ubuntu-tweak-testing/ppa
sudo apt-get update && sudo apt-get install ubuntu-tweak
