I always wanted to make such a tool for myself but never sat to actually build it. User experience was a breeze.

I see that there is no import button. Adding Import will help many of us to keep editing the same tree instead of building it from scratch everytime. You can add a JSON export of the tree and then users can import this JSON to make edits. I can also share this JSON with other family members.

Thanks for the feedback! I’m glad the UX felt seamless—that was definitely the hardest part of the project.

Implementing JSON import/export is at the top of my roadmap for persistence: letting users "save" their progress locally without needing a cloud backend.

I’m working on the data schema for this right now. Stay tuned!

Great, keep us informed and let me know if any help is needed.
