I want to request a new feature for a future release of blender. How do I do it?

I want to request a feature for Blender where you can have volumetric lights filter through transparent objects or textures giving you the sort of effect you see when shafts of light shine through a stained glass window in a church. How can I get this to happen. Any help is appreciated!

Did you even read a little down the page
http://blenderartists.org/forum/showthread.php?t=132753

Volumetric stuff is already being worked on that allows light shafts, Cuban developer Farsthary delivered the initial code and Matt Ebb (Broken) has been rewriting and enhancing it with a branch of Blender named ‘Physics’

NOTE: Branches are still the same program, but have features not found in regular releases until they get merged into SVN trunk.

A similar feature is actually in development.

But if you have any other ideas www.blenderstorm.org is good.

Edit: Woops, I was beaten to it.

Similar? I personally would rather have my lights making shafts through a foggy volumetric volume then just set it in the lamp, it’s more powerful for starters because it allows a lamp to cast shafts through some areas and not through others, plus you can use procedural textures.

Good point CD.
