LauncherPro here. At first I was happy with sense's launcher (I thought it was fast enough) but it's so twitchy. It's like the program really really "wants" to spin the carousel or pop all 7 desktops up every time you come near the screen. I think the sense launcher is about dazzle at the expense of usability.
Not to derail the OP's thread, but I am confused by LauncherPro's behavior in landscape mode. I have my icons in a 6x4 grid (I wanted 7x5 but that's enough of a side-track to warrant a different thread) anyway my 6x4 is fine in portrait mode, but in landscape it _stays_ 6x4 which of course is an absurd fit for the screen in that orientation. I ended up turning off auto-rotation so now I effectively don't have a landscape mode. How are other LauncherPro folks handling this?
