@uzer9896 It would indeed be nice! But we prefer to keep the app completely Internet free. This way, everyone can be 100% sure we don't do anything shady with your app list or contacts: KISS doesn't have Internet access, and you can check that at the system level, no trust required!
Last month, KISS released the biggest update in year, and a lot of speed improvements. Did you notice anything? Should we spend more time on speed, or features? :)
@007chaand You're probably using Amoled Black -- amoled balck won't let you set up a wallpaper, as the point is to be pitch dark for battery saving. Use standard black theme if you want a wallpaper!
