I am using the iCloud Drive, and sometimes the name of an app folder is too clumsy and too long to own a place on the Finder sidebar. Per the previous attempts by others, the Finder sidebar uses only the original folder name, but ignore the alias name for all its items. So using alias isn't a viable approach to workaround the name of app containers.
As known from the iCloud Programming Guide, the name of the app containers is actually specified by a key in the app-provided plist. The file hierarchy of the iCloud Drive does prove this, but the plist doesn't seem storing together with the Documents folder for each app. Is there a way to change it?
