How to create a materials library in Blender

[@josephburgan3D]

Thanks for the info. Do you know if there's a way to preview the materials on like a mat ball or something when you're in the file browser looking for materials to link/append? This would be perfect.

Is there something like Modo's preset window (F6) in Blender?

What about the Mysterious "F" in the material panel ?
