I have a couple ideas for some features that would really benefit the livery editor 1) the ability to preset road numbers, this would allow one off liveries to only appear on one unit, rather than a bunch, or you could have a unit that has a variety of siblings appear across a range of road numbers. 2) the ability to set what route the unit will spawn in. This would allow locomotives (eg, a CSX ES44AC made using the BNSF ES44C4) to spawn on the route(s) the livery is designed for (eg, said CSX ES44AC being able to spawn in the Sand Patch Grade timetable)
Another thing that would be good would be a way to create your own fonts and upload custom logos or shapes.
For custom logos/shapes , that's what I want most because it's tiring to create and recreate for each new livery, especially when they're quite complex. I would also add to have a control system for the percentage at which liveries appear because I've noticed that for some trains the liveries appear almost all the time (e.g., BR 442 on DRA/DLG) and for the others it's the opposite, rare or even almost never (Class 465).
