I am a user of KStars / Ekos since several years now but I just discovered (!) a very useful place to explore in detail its multiple possibilities:
www.stellarmate.com/support/ekos.html
This link is nicely designed and brings all the necessary hints to use the software : Setup, Capture, Focus, Guide, Align, Scheduler, FITS Viewer, Observatory, Mount, Analyze, Meridian Flip.
This is much, much more useful than the Help > KStars Handbook item found in the Help menu.
Therewise it might be neat to add a menu item Help > Ekos Support will a direct link to www.stellarmate.com/support/ekos.html
