I hope to get some time to fix that (along with several other issues).
If talking about fixes, there is one thing which bug me: box cars.
1. there is lack of specialised cars, for example for livestock only or refrigerated cargo class only. General purpose cars with autorefit option are sometimes very convenient, but sometimes utterly annoying, when they pick unwanted cargo.
2. changing liveries during autorefit looks weird.
I propose to add two separate cars: for livestock and for food (or other refrigerated cargoes). There is no much work, just reuse existing liveries for box cars, while keep boxcars with GOOD livery untouched by refit.
