Good to see Tangent getting traction!
Dormouse, I see you on the Tangent discord, great job at proposing features.
To anybody here using it: donate too. Taylor should be supported and he's building a piece of art. How many electron apps are actually usable? few. He's a really good programmer.

This one is also interesting: https://www.flowpilot.co/
'Start with the end in mind' sounds solid. Didn't try it for a project.
Tangent feels extremely good. They have solved a giant problem: graph view is useless on other tools. Not here. You build up the graph as you think. And see only the  parts you have just used.

It's very similar to how I used big paper to think.
