Adds an extra section to the friends list where you can add your most important contacts on Discord (Bots included). Add users by right clicking their name, opening their profile and then clicking on the star. Also displays VIPs at the top of your Direct Message (can be turned off in settings and group DMs can also be disabled in settings).
Uh since BandagedBD updated the VIP star is Missing and the option itself is missing. The section is there but nothing else.
