The pitch is that you can edit the flowchart in text straight away. So you can just use any editor and paste it and press "Apply changes", if you don't like the built in one.
Probably a few bugs left.
There is no backend saving state, so remember to export the sqlite file when you're finished.
I would love feedback if this is usable to anyone?
In that case I might bother building a backend for user data and buying a domain name.
