Since the alerts are slowly getting built upon, I figure this might be useful and a pretty simple concept. An alert for when enemies are inbound to a planet you have units/Structures on via orbital. Something along the lines of a popup reading "Enemies arriving at [Planet name] in [ETA]". The information is already there if you're paying attention to orbital movements, but it can be a pain to keep an eye on. Thoughts? Feelings? Wish to express your undying love to me?
I thought about the exact same thing before and asked if it could be made into a mod in the in-game chat but @cola_colin suggested I simply set the PIP cam to the map view.
The problem with that is that the orbital lines are essentially invisible, especially when you're in PIP. Aside from that, if more than a few things are transferring through space at any one time, the orbital paths, and being able to see what is going where quickly becomes a complete mess.
