Another new bug i found recently. The apps can be renamed but after renaming the apps dont get sorted alphabetically with the new name.. Example from India. My BSNL is a app for a the national telephone company. If you edited the name to just BSNL, the app remains between the apps names L and N but will show the name starting with B.
If you thought the idea of renaming is to bring the app to the top list- sorry, the UI thinks thats just a feature you can enjoy. The only option you have is to smart group.
