Our members would love more personal options in their profiles such as these:
Ability to ignore a certain person's signature.
Ability to disable the preview popups.
Ability to disable the username member card popup.
Ability to toggle avatars.
By having the ability to turn these on/off at will, members can adjust their own settings to their preferences without having to affect the entire overall forum. Also, it's a great way to keep multiple sides of the member base happy.
