I’ll check this out. The macOS photo library situation is really embarrassing. I actually migrated from Affinity to DxO Photolab (expensive!) a few years ago just for that.
Unfortunately I have time to build only the software that I need, and I'm a Mac user. If I'd do a cross platform version it will end up like the other crappy cross platform apps out there.
As someone who has had to use Creative Cashcow tools in the past... dare I ask what the hell was Bridge even for? Just an Adobe-developed file manager?
Seriously, what the hell are you talking about and why.
