One suggestion would be to add the "Install Option" like on vBulletin.org for template edits. I suppose it's really just a modificaiton on the "subscribe" feature, but it would be cool to look at all the modifications that you've installed on your board.
I guess I would really like to see this feature because I'm creating more and more forums and it'd be good to easily figure out what template changes I've used in the past.
As Xelation said, it may or may not be added. As it stands, that hack was made for vBulletin.org only (by FireFly or another hacker), so I do not have access to the hack.
