Similar to the option to turn layers on and off for each route, how about a screen to control which liveries appear? It would make a lot of liveries more appealing - ones that I like the idea of but don't download because I don't want them to appear on certain routes. Equally, it could help us better understand why some liveries appear and how often - I find there are loads I've never seen, yet the couple I have for Brighton Mainline seem to turn up on almost every train I pass.
Suggested this a few times - it really is required. Immersion breaking to see a GWR liveried 801 passing on the ECML, but not for a celebrating Scotland to pass!
