I posted this in support...but think that this is a better forum to request this.
I love PM and for me to be able to keep using it in my workflow I need to be able to open .mos files.
I hope it is possible to add this feature....Leaf is very supportive in providing information.
We may do that in the future. Leaf has indeed provided the information to us. They even recommended we use DCRAW to render Leaf files. Unfortunately DCRAW's demosaic algorithm is fairly poor and moreover it is fairly slow.
You said in the other thread that you would want to show previews to your customers, so I'd guess that quality is of some importance. The open source solutions out there would likely disappoint you. Writing a RAW converter is just not an easy proposition. If it were, we would have added it as an option long ago.
