I’m impressed.
Threw at it a very casual panorama (all hand held, done in a hurry):
and got a very nice result:
The yellow boat was a curve ball, very well handled (no undue extension), even if the wake could have been straight…
My only (slight) worry is that when exporting to JPEG, the chroma subsampling is the harshest there is. An option (full/halved/quartered) would be definitely welcome.
