I am sure this is a trivial one, but when I open a fits from the file manager (Dolphin, KDE, Manjaro), a new instance of Kstars is started from which a FITS Viewer is displaying the image. Any ideas where to configure this properly so an already running KStars/Viewer is utilized?
So this is a bit tricky.. I always wanted to re-use an existing KStars when I first implemented this, but didn't know how to do it and just forgot about it as a "TODO" item later. That was a couple of years ago.
If anyone can figure out a way, that would be great. Kate does it, but I think there some dbus magic going on with session management.
