Feature Request: "It is not possible to display custom data on the main map itself."

[esemwy]

Please consider changing this.

I use travellermap.com live in my game, except when I need to add custom data. Then I'm reduced to paper handouts. It makes me sad.

Alternatively, how hard would it be to port to Nginx/Mono? ;-) Actually, I'd consider contracting someone to do this.

Maybe a browser extension could be contrived?
