Any Photoprism user out there that tried this already? How does it compare, UI and updating-wise? I'm a Photprism donor but seems that development is stalling a bit lately (just a new release in over 6 months and with not so big changes, although I still have to update to be honest) EDIT: after a quick assessment in the doc pages/features, this seems to... blow Photoprism out of the water?
