I second, third and fourth point 1 above. I just used Affinity for stacking and it was very painful to load up all the files - then not be able to save the file set for future reprocessing. This is absolutely something every astrophotographer does, frequently. The lack of a load-up mechanism for multiple files is a serious omission. Also, the method of loading files is very cumbersome. Affinity Photo doesn't 'remember' where darks, flats, lights etc are stored, so I have to browse to each type every time. There's also no way to assign one set of calibration frames to multiple groups, so for example I can't use the same flats across different groups, I have to load them up every time. APP has the best interface for this, just load everything up and then tell it what matches to what using checkboxes. Maybe try a trial of APP and see what I mean! I get the feeling the stacking option is fairly new, and look forward to it becoming more sophisticated so it can contend with the likes of DSS, APP, Siril and so on.
