Only a few for hunter that I've seen
Venantes 2 RC6 is like a easy access button mod I used it for a bit.
I've not run into a lot of Mods just for hunters that I've really liked.
Here are some nice macros that are handy
Feed Pet
/cast Feed Pet
/use Wild Hog Shank <- or whatever food you use, just type the name in
Easy Mark Attack
/cast Hunter's Mark
/petattack
these basically makes what was two clicks or so One easy click. I use these a lot.
