No problem Nik, I expect you’re very busy.
Perhaps it would be possible to include a button for rotate on the main toolbar in a future version? I find that when I am rating photos I usually do so with the info panel open because I like to see the camera settings and creation date, location etc. When I come across an image that has the wrong orientation I have to switch to edit, use the rotate command, then switch back to info which interrupts my flow somewhat.
Regarding multiple access, if I edit an image on iOS which is in the Files app (rather than Photos) will those edits be reflected on my Mac when accessing the same folder?
