I like TukUI. Automatic configuration of the user interface so you don't have to change stuff in your wtf folder for your resolution(If your resolution is supported which is most likely is).
A lot of nifty configuration you can do and it's customizable to however you like if you know a little Lua.
That and mage nuggets.
I honestly don't use that many mods for my mage as I use to. For portals and teleports I just type it out..
