Most tools keep your ideas, to-dos and links in separate places. Here they share one tree. These are small working demos, so poke around.
Every idea can hold more ideas. Break a big thought into parts, open any part to work inside it, and step back out through the path above.
Try it: open Hotels, add a place, delete one.
A checklist is just another node. The count shows on the branch, so you can see progress without opening it.
Try it: tick the rest of the list.
Save an article or reference right where it belongs, instead of in a bookmarks folder you never open.
Try it: paste a link.
Mark what matters. Prioritized ideas rise to the top of their branch.
Try it: tap Set on the last task a few times.
Vault notes are for things like passwords and codes. They stay hidden on the screen until you choose to reveal them.
Try it: reveal the note, then change it.
