I think that having the custom profile shop option on the in-game store would be nice.
Personally I find it inconvenient to have to go through admins to get custom profile work done.
Maybe the custom items thing would be a little harder to do in that sense.
However having things like custom user titles, pfps, and name changes would be quite nice on the in-game store section.
Let me know what you guys think of this idea :3
