This is an idea for testing the dyes on every piece of the armor, weapon and costume simultaneously in a single window.

Re-edited the window and replaced the Show check-boxes with a Toggle View button and added it in the weapon and off-hand too thanks to the recommendations of MithranArkanere and Xiaquin.
Also I changed the positions of the weapon, off-hand and costume headpiece and body to resemble like the inventory.

Added a show/hide box for the cape. (Thanks again MithranArkanere)
