Light gray stained glass panes are nearly invisible.

This is merely an improvement that I recommend. In your inventory, light gray stained glass panes are practically invisible. This is a little annoying and could be easily fixed with a slight texture change. As you can see in bottom of the picture, I have light gray stained glass panes in the left side of my hotbar. However, in my inventory screen, it is very difficult to spot them. It would be greatly appreciated if you would alter the texture to be more noticeable.
