Simple Gallery Pro vanished from F-Droid, any similar alternatives?

F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.

Otherwize there is another (very IMHO) good alternative FOSS gallery: AVES
Aves handles tags very well
Aves is amazing.
