Going further

Show one section in two places

A mirror shows a bullet and everything beneath it somewhere else in your outline, live. Edit it in either place and both change, because there are not two of them. There is one bullet being read from two directions.

A mirror can point at a bullet in somebody else's outline, and it stays current as they work. That is how two people share material without either handing over control of what they wrote: their section stays theirs, in their account, and yours shows it as it is now rather than as it was when you copied it.

Deleting a mirror removes the reference and nothing else. The bullet it pointed at, and everything under it, stays exactly where it is.

Tags, mentions, and finding things again

Write #anything in a line and it becomes a tag you can pull every other line by. Write @someone and it links to them. Paste a URL and it becomes a link. None of this is a separate step or a field to fill in. It is what happens when you type.

Search runs across every bullet and every note, and shows the match highlighted in the line it was found in. It matches words, so you do not have to remember how you punctuated something eight months ago.

Notes and comments

Any bullet can carry a note underneath it: the paragraph the one-line summary is standing in for. Press Shift Enter to open one. The line stays short and scannable, and the detail is a keystroke away instead of a document away.

Any bullet can also carry a comment thread. A comment is somebody else's writing rather than yours. It lives in their account and stays theirs, and you decide who is allowed to leave one.
