As there are no longer any sectors I often times have a terrible time finding planets back and have to sort through them one at a time.

There is no option to do this with ship yards or starbases.

Can we get a minimap built into the UI someplace that perhaps zooms in and shows the planets or things in like a 15 hex radius of the planet/starbase/shipyard we are looking at?

Id suggest sticking it over to the left over the orbital planet view stuff that is currently in the UI.
