I have installed both Panda and Open Home a couple of times and deleted them. All I wanted was extra home pages, nothing else and I could not figure them out. This was a while ago so maybe they have been updated and maybe I have become more savy but I haven't tried them again.
I have turned to App Organizer so O can put, for example, all games under one icon (folder). I'd prefer the extra pages, on for games, one for travel, ect., and maybe I'll try it again some time.
