Hi — disclosure: we’re developing Novira’s Katha writing studio. We are not asking for sign-ups here; we’re trying to understand real writing systems.
Do you use a wiki, notes app, spreadsheet, character sheets, or something else? What is the first continuity problem that tells you your system has broken?

Clearly not a Star Trek fan…
I was riffing on Picard’s epic “the first duty” speech in the episode by that name.
