/**
 * update_tablet_open_uis
 *
 * Will search the user to see if they have the tablet open.
 * If they don't, we'll open a new UI depending on the tab the tablet is meant to be on.
 * If they do, we'll update the interface and title, then update all static data and re-send assets.
 *
 * This is best called when you're actually changing the app, as we don't check
 * if we're swapping to the current UI repeatedly.
 * Args:
 * user - The person whose UI we're updating. Only necessary if we're opening the UI for the first time.
