One thing I currently miss in Ekos which could be a good starting point for a planetary tab IMHO, is a simple live view with gain, and offset (sliders), zoom (used with a Bahtinov mask), a crosshair (used to align a guider and the main scope) and a large window to help roughly collimate a Shmidt-Cassegrain when you have your hands on the Bob's Knobs, far from the laptop.
In terms of ergonomy, that would be a game changer
