Can't loop back from one state to the previous state clearly

[lastmjs]

Let's say there are two states, q0 and q1. If I have a transition arrow from q0 -> q1 and I also want a transition arrow from q1 -> q0, the transition arrows overlap each other and it is unclear which transition goes with which input. It would be nice if the one of the arrows curved or something.

Did you try dragging the arrow? Arrows between states will curve when dragged.

Ah, yes. That wasn't intuitive to me, maybe it could be documented on the page? Awesome tool by the way!

I'm adding on to @lastmjs 's request to add the arrow-dragging feature to the documentation on the page.

The current description on the page is

Move something: drag it around

I propose that it be replaced with

Move a state: drag it around
Curve or move an arrow: drag it around

or something similar
