Member Profile Page Customization would be a great add-on and totally worth your time as none previously exists. A lot of xenforo users come from vbulletin 3 and vbulletin 4 forums where member profile customization such as the ability to add our own background image, change the colors of font and blocks or a music playlist to our forum profile page is a must-have.
This is something I was actually making for SMF for an old client. Basically myspace customization done right. It is definitely something I want to do however there is a lot on my list and this would be a big undertaking. Hopefully sales increase so I can work on mods more and possibly pay someone else to work with me.
