This is a really handy UI mod that I swear by. It has little clickie buttons to toggle harvesting nodes on and off, as well as zoom in of more detailed maps of cities (New Targonor being a really useful one). It has a ton of other useful little features too, which can all be toggled on or off depending on what you want.

Oh, you can also move all your stuff around on the screen by going into Settings:Interface and then ticking Layout Mode. Can move around things like your hotbars, map, monster info display, all that good stuff ^.^
I bring that up because installing the mod can leave the new buttons in weird places depending on your resolution and you might want to move them to a better place.
