I've used prior versions of kstars for 18 months or so, but setting up a new rig I've ended up with kstars 3.6.3. I cannot work out how to setup optical trains. My camera is connected to Indi fine, but when I start ekos I get to this screen:

which looks nothing like the picture shown in the documentation videos. I can select components fine, but clicking "+" does nothing. If I close the window then no optical trains are defined so I cannot take any shots etc. How do I add an optical train?

Hello, is there any specific reason that you do not use the latest stable version?
