a slot to pick an item to color your train (and stations) with, sliders are nice but I like the item colors. bonus points for effects glowing green uranium train

also no offense to the backers but I would really like to name my trains as well

You can get your name on the trains in your games, just not in public release as they promised that to the backers exclusively. To add them in your game just add your name to data/core/backers.json. There are over 3000 names already, so it may take a while to find it!
