It seems like every time I come to this thread I find another quality mod that is very useful and coded well. The durability mod I was using before was a Cosmos mod that wasn't reporting my durability correctly. SLDataText is a very clean and simplistic way of showing just the data you want to see and you can disable the rest without using a whole plugin bar that takes real estate at the top or bottom of the screen. It fits in very nicely with the current version of nUI.
Of course, I have it in the back of my mind that many of the mods that I am using now to compliment nUI are being planned for inclusion into the base UI so hopefully someday we can dispose of most of these mods.
