This is my first GUI.
I've been making this GUI because lately people have been making all kinds of crosshairs and I thought it would be nice if you could change them in-game using a nice GUI with 'preview' images of the crosshairs. At the moment you open the GUI with F6 and then you can choose from the assortment of crosshairs. This add-on works on ALL servers since it's a client-sided add-on.

The crosshairs from the GUI are all made by Block Builder (Tc572). The default crosshair that you see in the Custom section was just for testing, when you click an empty slot an error message appears like so:

You can add new crosshairs to the Custom crosshair list by going into the .zip and then navigating to the Custom folder and then add a new crossHair.png image to one of the folders that are labeled with numbers.(1,2,3..10) [./Client_CrossPick/CrossHair/Custom/#/crossHair.png]
Constructive criticism is allowed.
