My problem is not how I define a collection. The difficulty I have is that in any collection, you can arbitrarily re-shuffle the images, if you choose custom ordering. What I’d like to do is save the order.
Say, you filter out 100 images by defining some collection. I can save those rules as a preset, that’s clear. Now, I re-shuffle the once, and that sequence is then saved in the darkable data base, so next time darktable can recover the view. But what should I do, if I want to try out 10 of these orderings, and want to compare them? Where can I save the sequence?
Is this something that I should be able to do with scripting?
