from Eric's chart is not clear to me where Ekos ends. I mean if 'frame DB index' is meant to be part of Ekos or an external software? I will eventually post on that thread for clarification.
I think we do need more active developers at KStars side to implement such features.
Many of us would like to help implementing new features but Ekos has a steep learning curve, partly because of its internal API and partly because it's C++.
I think that find a way to lower the complexity of the system would help increasing the developers base.
