What the six tabs do

Four of the six aren't named after their job — Calibrate is Settings, and that's the one everybody hunts for. Also covers the Review queue, the settings worth knowing, and why re-parse and re-ingest are different buttons.

Three guides, because it's three jobs.

Your dashboard — the tiles, and the two controls that change all of them at once. Including why All means 365 days rather than all time.

Sharing — private by default, and two separate levels: who can see you, and which categories they see.

Settings — the account pages, and the one setting that leaves tiles empty until you save it.

That's a different page.

Troubleshooting covers the six things that account for most of it — two of which aren't bugs and never will be.
