Tinted glass is not considered a 'Functional Block'

Tinted glass is considered a building block in the creative menu. While this is true, the changes allow blocks to be in multiple categories. With that said tinted glass should also be in functional blocks as people use it with farms. The function would be filtering light.

 

There's also an argument to be made that it should be included in the Redstone tab but that is far more iffy.
