Would really like to see a way to differentiate between edited and not-edited photos. Either an icon, or preferably a way to filter. This appears as an option in the iOS app, and in Lightroom Classic CC, but isn't an option on the desktop version of Lightroom CC.
Filtering on edited/non-edited photos is possible with the latest desktop version of Lightroom CC. You can type "edited:" in the search bar and choose from the options that gets listed in the suggestions popup.
