I think that the little map in the top right of the screen should be 3d. Or in other words Add a Z axis to it. It would be helpful

That would help a lot in a few interior maps.

Before 3D mini-maps are added the ones we already have need to be increased in resolution for when zoomed in.

by what gods may be... YES to this idea!
that minimap looks like something from a 90s era rts.

and even back then 3d maps where available.
colony wars, g-police and homeworld all had minimaps/radars that make the one in sto outdated eyesore.

And how do you suggest that work?

check out youtube lets plays of the games i posted as example & look at the maps/radar they have.
