Feature request, allow to process all light and flat files of different filter all in one go, so APP recognises filter keyword in naming or in fits and will create master flats for all channels, calibrate all channels and register stack all channels in the same workflow as you go through the different steps, huge time saver. You can always leave this optional for those who want different settings for different channels (it would be easiest to make a selection when loading the files, here you just load them one buy one but if you load everything APP could do it’s magic automatically if you check the option)
