FYI - I just made a similar inquiry on another board. The developer for Launcher Pro is no longer working on it, so if your's still works (mine is very buggy) you can use it but there won't be any more improvements made to it. I'm guessing that ICS will seal its fate. It's really too bad because I loved LP on my DInc and couldn't wait to put it on my Rezound when it arrives on Thursday.
It's nice to know that Sense is out-performing LP. I'll definitely have to play with it for a while before I judge. Right now I have Go Launcher running on my DInc and I really love the functionality, but it causes major lag. I'm not sure how it will perform on the Rezound, but if I love Sense I'll just stick with that.
