I will be looking into adding more items etc but depending on the coding required will depend on if it will be a add-on, I will look into something along them lines
This functionality is very common, and is also desired by my community. It is provided for in Xenforo's shop add-on, as well as many prior shop add-ons over IPS lifetime. Basically, graphical items for the post bit and profile. They can be purchased and traded. Users absolutely love them. The ability to re-arrange the display of these items, and to pick between, say, the top 10 of them to display in post-bit is lovely.
I have also requested, multiple times, as have many other users, the ability to buy access to additional usergroups. We like to maintain one primary group (member or staff level) and do other privs as additionals.
Finally, @TheJackal84, members shop is completely broken on my board and results in a Error: Call to a member function url() on array (0) error. I provided more information in PM to you yesterday.
