Mastodon Feed
If you are ever in the position where you are the steward of a user's consent for software to access their data, make sure that the user gets to remain in control of WHAT data is exposed. Which mailboxes, which calendars, which photo albums, which contacts. This does need to be high-level; as users do not generally want to be forced to do complex configuration as *well* as clicking through a bunch of dialogs just to get their work done, but it is your absolute duty to *give them the option*.
