Satellite confusion was created by Andrew

I'm new to EKos, so while this may be obvious to some, it wasn't for me and perhaps should be better documented.
I was trying to get satellites to appear, and for a time was frustrated that updating TLEs would clear the list of satellites I had chosen after having updated satellite orbital elements beforehand.
I know now that I must first select the satellites I wish to track and apply the changes before updating satellite orbital elements, and finally update TLEs. It just not at all intuitive.
Adding a button to update orbital elements in the Satellites section of the KStars configuration next to Update TLEs would probably help along with better documentation.

I would also like to echo a wish to implement satellite mount tracking features with both differential tracking rate control and leapfrogging techniques for mounts that don't support differential tracking. Perhaps even implement some computer vision smarts to search for and identify the moving target in the vicinity and keep it centered in a finder FOV.

Yes I fixed that so that it saves the list before updating TLEs. Updating Orbital Elements and updating TLEs is the same thing. For the last feature, is this something you would like to contribute to the project? If yes, it would be great!

Excellent thank you.

As for satellite tracking feature, I would love to contribute if I could. But I don't have the skills to do so.

This looks amazing. Haven't tried it yet. But I can tell this is some nice work. Is it possible to enable GPSD for automatically setting location? And can this work while offline if I update the TLE's from space-track first?

I have installed Python 3.x. It is version 8.1.1. For some reason the upgrade command to 9.0.1 is downloading the upgrade package, but installs version 8.1.1

I forgot to mention that python 3 was required. I am still working on it and I will write the documentation when it will be finished.

Has anyone tried it? Could you give me your feedback on the tracking ?

Just with the simulators, works so far. Waiting for clear sky for a real test. I recently tried to catch a
satellite in kstars by slewing to its track some minutes before it enters the field of view. But I did not find it
in the exposure. Maybe it was not bright enough or the track was wrong or something else... I'll report back on success.
