Theme with at least some indoor support?

[lega4]

I see a lot of themes around here are focused on outdoors usage, which is great. I'm myself using Elements for years now and quite used to it. However it gets a bit messy when getting in the area with some proper indoor mapping done.

Probably improving indoor view is not really a focus for outdoor-focused themes, so my question would be - is there a good theme which is focused on indoor navigation?
