This is the Sony Ericsson home launcher app from the Xperia Arc, ported to Galaxy Ace. While I was initially not so keen on trying out a stock launcher (owing to the fact that I dislike TouchWiz, and not a fan of Sense either), this one feels pretty good, mostly for the fun animations – the bubbles at the corners, the dragging of icons, the trash can giving two vibrates while closing the lid after deleting an app, and more. True, being a stock launcher, it doesn’t have the amount of customization options that ADW or GO or LP offer, but doesn’t hurt to try out.
