Yeah I was really excited about Open Home so I got it and installed it and it looked great, installed a few themes and icon packs, setup 5 out of my 7 screens, everything was great but it ForceCloses too often for me. That was the ONLY issue. It was NOT laggy, it wasn't "stretched" or anything for the larger resolution, nothing like that. The ONLY issue was the random forceclosures. Once it is a bit more stable I will go for it.
Also, please note that if you get the lite version, it is nowhere near as feature rich as the full version. The lite version only lets you use like 3 widgets and no icons or something if I remember right. The full version has a LOT of options and you can use all the normal widgets plus like 5 or 6 OpenHome exclusive ones.
It is an awesome app and I'd have it installed now if it didn't FC so often
