noticed a lil bug, probably cm9 related rather than arco's build.. if u have a shortcut of an app on homescreen, and u uninstall that app, after some time u can see the app's icon again on homescreen, but the app cannot be found anymore in the app drawer or app manager. happened to me on 2-3 occasions, but i guess it's random coz i can't reproduce it for every app
Have you noticed in which version the trebuchet launcher is? It's an alpha build, so for now it might be a good idea to use something like apex launcher or another enhanced stock ics launcher
