Better syncing for photos
I recently learned the hard way that the Sync Feature for photos has a limit thats rather low. When i hit 1785 photos, the sync feature stopped working. This is a very low limit that seems to be set at the software level.
A more reasonable limit of something like 50,000 or so would be a great idea. Some people use OneDrive exclusively for photo storage, so a low storage limit really hinder that.
