I want the tool you're building! It's got huge overlap with a project I was just in the planning phase of, a cloud-ified FreeMind. However! There's one fatal-for-me flaw in your current implementation: only three layers deep. Deal-breaker. I'd love to hear about it if/when you change that behavior, so that I can start trying this seriously. I saw your comment about future possible options to self-host, or offline mod…
Thanks for the feedback!
Yes, more than three layers deep is our highest priority, along with offline mode.
And you are right, I meant "depth-first"; makes more sense.
