Sorting for the Log In Screen
When you log in, your characters from all the accounts linked to your Master Account are sorted by LVL, going from highest to lowest. It would be ideal if you could pin certain characters, like your "main" or that character you just made and want to focus on for a while, to be on top of the list. Maybe even add an option to sort them by Game Account, or Alphabetically.
Just a minor QoL improvement, having more than 5 characters and needing one in particular, making you go through the list every time, is a pain.
