Kudos to some fine app development.
I've given the cleanmgr+ app a whirl - found some aesthetic issues:
1) If the cleanmgr+ app is started for the first time, the windowed screen cuts off words at the bottom if you enable Show Description in settings
2) In same windowed mode, slicking preview cuts off text as well.
3) Vivaldi browser name is misspelled (+ more menu).
Keep up the good work, though, this is a good start!
