I’ve only just discovered Darktable, so I was a bit reticent to call it one of my favourites, but for the relatively minimal editing I actually do, it does seem to be pretty ideal. I only use Digikam for organisational stuff really - do you find that Darktable’s filing/cataloguing ability is good enough that you only use the one program?

I’ve been liking Digikam and Rawtherapee (which is an awful name for the record) for photo gubbins.
