Would make an awesome addition and they can have three immediate versions
Affinity Editors Edition
Affinity Photo (Pro Studio Edition)(Any Camera)
Affinity Photo Studio(Selected Camera License)
I would for a fact work on development of this and surely would pay let's say $85 for additional licensing... no subscription crap and I hope they don't produce subs in any future versions down the road. But no competition to Capture One or anything, but for quick jpg sessions where you are not heavy posting, this would make great for quick location settings.
No forced "catalog" nonsense. Just simply a new session(or if one is open, you can start/continue on that with no hitches) ... and start firing away.
