TL;DR
There should be a hotkey to copy/paste a train with fuel without entering the blueprint dialog. I propose to add "Shift" key when doing Ctrl+C.What?
If I have a train on a rail and I want to copy it, I must either- a) manually construct a train, manually fuel it, and manually copy the schedule (shift right click, shift left click makes this a bit less painful)
- b) create a new blueprint by holding shift AFTER pressing Ctrl+C to enter blueprint-selection mode, then check "include trains" and "include fuel", store the blueprint in my inventory or bp book, and then finally use the blueprint
