progress indicator or cancel button when applying CPU intensive tasks
New darktable user here so apologies if this contribution is inappropriate.
I've been pasting a history stack on 100 images and I realized there's no obvious way to check progress or cancel that kind of action. This could be bad if, by mistake, I paste some complex stack to, say, 1000+ images.
I think some way to cancel CPU intensive tasks is needed and a progress bar would be very useful.
