Route network map -- filter by base

[LemonButt]

The route map is cool (https://www.airwaysim.com/game/Routes/Map), but it's largely useless when you have bases overlapping and lines everywhere.  I've found this to be even more important when it comes to cargo and finding catchment areas I'm missing and/or competing with myself with multiple flights.

The feature request is simple--add a box at the top right similar to the airport view for showing squares/airports that just filters the route map by base so you can see the routemap on a per base basis.  You can quasi do this with the airport route maps, but with the destinations you don't fly to it just pollutes it.  I'm guessing this is a simple feature to add, but is probably more complicated than I think...

Would be very useful indeed.

In addition, There could also be a box on the airport route map to filter it by airline. Two different ways to get the same result.

Agreed, would very much love to filter the route map by base.
