TL;DR
When in train view, the map settings should be consistent and persistent.What ?
In regular map view, the map settings are persistent - things like pollution on or off, train stop names on or off, player names on or off. In train view, you can now see and set the same map settings, very nice QoL.However, the map settings are not consistent between train view and regular map view. I can adjust the settings in train view to be consistent with my map view, but those changes do not persist, so every time I open train view I have to redo my changes, or do without.
Ideally, the train view map settings and map view map settings should be one and the same.
