Yup, I could
The only prob is that slidesound works by looking for changes in the screen orientation.. So say your video player switches to landscape to watch a movie, you would get a text msg window over it, hehe. I've been thinking about expanding it a bit to include that, but that's the biggest drawback.
I could always just add it anyway since it would be optional. Opening the app would be easy too, but minimizing it a little trickier.
