In the past, many of my linux machines had a desktop that was bigger than my screen resolution. For example my desktop could be 3000 x 2000 resolution on a 1024 x 768 screen and by moving my mouse to the edge of the screen the desktop would scoot over.
I have a 3.5" touch screen on my Pi 2B running at 480x320 and many apps open up bigger than the screen resolution with no way to even close the app. Is there a desktop or window manager for pi that can scoot around the screen with the mouse?
