I have a really basic though. As you may know, trains have different sounds on different type of rails (standard rails with ballasts, tracks concrete panel ballasts, bridges, tunnels...etc).
It'd be a really great thing if this could be reproduced in LOTUS. Maybe an extra variable in the rail splines (type), and a new global variable for that in the vehicles (like the init ready and the others).
Also will there be a vehicle delete option in the alt menü in the game, like the new vehicle, time settings, display info?
Another thing which would make a difference is the format of the print screens in the game. Maybe there could be an option for saving in jpeg rather than png (all of the screenshots are about 2,5MB in full HD, that's huge).
Also, what if the quick start used the same time settings as the saved state? I mean if I try out somehting in the daylight, then quickcstart it later that day, the game always loads according to the real time, which means if I reload the situation in the night, I always have to reset the time.
