When the API is down and Recursion is forced into offline mode, it requests a player id. It's most likely that most people want to track a player they've played before, so Recursion should offer the ability to select from a list of known / recent players.

(Not sure whether this is possible, but could it provide the option to not ask at all and just use the known player list to automatically pick up which character you're playing by whichever id is spotted in the event stream)

Additionally, it would be helpful if this dialog described where to find your player id (or provided a link to documentation if it's too long for this dialog).
