Stained glass panes cannot be crafted from regular glass panes.

It is strange that you cannot get 8 stained glass panes from 8 regular glass panes and a dye in the middle. People that end up crafting normal glass panes end up having to smelt sand, just to get some stained glass panes and is also a waste of resources. Plus, it is possible in reality to stain glass panes aswell, instead of only being able to craft them from normal stained glass.
