Sorry about the poor video quality, did not have the HQ camera to hand but you get the idea of the app. slidescreen replaces the stock Home app on Android, works quite well and you can choose what it shows and how often etc. I've tried teh other Home replacements but never liked them. This is the most professional and functional. Some Market comments say it runs slow on phones like the Nexus One but I don't know how because it runs fine on my 32B HTC Magic running Cyanogen's ROM (4.2.15.1).
