I've been using Panda Home a while now. Works great, as long as I don't turn my phone off. Have it setup with 5 screens at the moment. 4 dockbars. Apps Organizer shortcuts on Main (center) screen, widgets on the other 4 screens. Layout is perfect (for me). BUT, when I turn the phone off and turn it back on, all my widgets stop working. I have to completely remove everything and completely rebuild my layout to get it working again. This is BS! And yes...there are occasions where I do need to turn off the phone. Also, I still get the occasional black screen with PH, as well as some occasional lag when swiping from one screen to the next.
Noticed someone mentioned that Open Home seemed to have improved, may give it another shot. Played with GDE a bit, may give it another try also.
