To put it nicely: you're not the target audience. This is the astronomy equivalent of the $50000/yr bespoke mechanical engineering simulator. This is not an outreach tool (or a citizen science tool). You don't take this to a dark field with a telescope at night (it's not a skymap), this will be used on a big screen to plan observations, or at an observatory (where you'll have at least 3 screens running). These kind of applications are developed with deep and continuous input from their users, and there's nothing superfluous there.
