OmxPlayer Gui for the Raspberry Pi

Omxplayer is the best audio and video player for the Raspberry Pi. But it's command line driven. You can use the arrow keys to advance or go back 30 seconds, press space for pause or q/escape to close.
I wanted a nice gui that did the same thing. Something simple with either buttons or keys. I could double click on a file and play it.
I wrote this OmxPlayer in C#.Net on the Raspberry Pi with Mono Develop. To run it, you need mono installed. Here's a link to the program:
To install it: The OmxPlayerGui will run whenever you double click a mp3 or mp4 file. The keys that control it are space, arrow keys, q, escape, + - (volume)
