Just wanted to pop in to give my vote for a linux port. I've using Affinity for the last couple days and I'm getting better results and faster than I get with Darktable, especially in noise reduction. If there was linux version I'd buy it now.
P.S. Would it be possible to make the trial version count the days that the program runs, rather than the days elapsed since installation? I was on the go for several days, so I missed a few days of trial use. This wouldn't help me any, but it would be nice for future interested parties.
