sounds like a nice thing if it would be able to be automated :D

I've thought about this too, it's possible it could controlled by a signal be but haven't thought about a way of implementing it.

My focus initially was just making it much easier to lay belts the 'wrong' way and then reverse them, or reverse an old line that you need to run the opposite way now.

Can it be made to fix belts where one segment is out of alignment: I.E. running right when it should be running left with the rest?

Zentriffic that's possible, however you can achieve the same thing by reversing the entire belt a few times. It's not a bad idea to have the option as its own hotkey, so if you raise a github issue I'll look into it.
