Rush has a few audio programs as well as a paint program.
Rush includes a very nicely done icon editor, as well as a text viewer. Surprisingly there is no calculator included.
All applications contain file dialogs which makes finding and working with files much easier than most other GUIs.
Bells & Whistles
The graphical installer for Rush should be the benchmark for all other GUIs.
"Proobs" is a categorized program launcher. Using the included icon editor you can make more icons and Proobs itself has easy options to add more shortcuts, and of course the file dialogs can be used during this process. This makes Proobs easily one of the best launchers in any GUI.
You can set custom colors, custom wallpaper, you can even draw your own wallpaper. and it's all done in easy-to-use GUI based tools.
Rush is a great GUI. The launcher leaves nothing to be desired, and there are enough applications included to keep you interested. With a couple more applications, maybe a game or two, Rush could be the best GUI ever made.
