Popular homescreen replacement Nova Launcher has just hit version 2.0 with a whole bunch of notable feature adds and improvements. The free version gets most of the improvements including custom wallpaper cropping, increased maximum desktop grid size and an infinitely scrolling app drawer setting. There's also a fix to force wallpaper scrolling on U.S. Galaxy SII (S2) variants, as well as a setting to force the phone to keep the launcher locked in memory.
As for the paid "Prime" version, users can now set custom icon sizes and use their swipe actions on any homescreen, rather than just on the main one. You can give the new features a try by downloading Nova Launcher at the Google Play Store link above.
