I also wonder if someone checks what the news says before posting it. Everyone posted something here?

How this works exactly?
Nah, don't tell me. Otherway, the news will be flooded even more.

I googled a little bit and found an interesting site about this extension:

I think it's useful when you want to draw alpha transparent objects but you don't want to care about the order. This extension will do everything for you. Right? But if it really has benefits..

See you,
