It was not my intention to seem disrespectful. I can understand that people have a need of a slideshow viewer. I just don’t understand how the majority of the users are not better served by a separate program
Features in software are like puppies. If you adopt them you have to commit to taking care of them for the rest of their lifespan. And programs that have many features are harder to maintain that more lean ones. I would rather have a leaner but more bug-free DarkTable than the opposite.
The examples you gave of other features are not the same. You could print from another program. But it printing from DarkTable make sense if you a) want to print as fast as possible, and b) print from the same computer as you develop your photos. I think that goes for most of the users. Personally, I would like to print to my photo printer from DarkTable but can’t because the of some bug I cannot diagnose.
Secondly, the map feature is not only for viewing your pictures’ geo-data But also for assigning geo-coordinates in a intuitive manner. Since we want to assign metadata as early in the picture processing pipeline (ie before pictures are developed and exported) it makes a lot of sense of having a map feature in DarkTable.
As for the tethering option, by having that feature in DarkTable you could auto-assign styles and presets to the pictures as you preview them. That would not been possible if you used a separate program for that.
