I have simple idea - that minimap could have settings dialogue like vehicle list has its settings dialogue for filtering. I think that would simplify handling the minimap - and adding new settings in future.
This idea is based on finding that displaying of factory's consumers is missing (in version 5804) - and instead of it is option of displaying of routes plans - that needs such settings dialogue - because currently, when all routes are displayed, it is a bit chaotic. I think that choosing of one or two (or so) types of vehicles (ways) would help.
This is still there; it is just activated when not routes are activated.
And I am not sure that separating would really help. But maybe it is my style of player. I need this very often with different options.
