nice! i love the design system & overall UX! some thoughts/questions:

- i wonder if it would be more useful to be able to branch out from some previous message in a thread, vs being forced to branch out from the end of a thread. feels more natural to go back and branch out into some tangent/deep-dive.

- maybe there could be some autogen'd suggested branch-out topics/prompts?

- does the top-level chat composer input have context of other nodes on the canvas?

- is there a way to search across nodes?

- how do i delete a node?

- are there plans to try to unify this canvas experience with the primary duolingo-style course flow? if so, how?

would you mind sharing why react flow over d3?

this is how my brain works!
