I´m new to darktable, been only using it for a month or so but I think this is an excellent piece of software, hats off for the developers. I was about to replace Lightroom when I found darktable.
One problem that i ran into was that I could not setup a Collection and make the sort order stick. Maybe I have overlooked something but I think I have read the manual quite thoroughly and I could not find any clue to how to do it. The problem is that I have images from my camera which i sort by date and I also have scanned images which I sort by filename, I also have a few directories custom sorted.
So, have I missed something or is this by design? Oh, sorry, I am on Win 10 Home and darktable 2.6.0.
