Was wonder if there was a material organizer/manager script? Like, you can delete/unlink materials, edit them without needing to select the object a material’s linked to, etc.
You could get your desire with this one http://peter.cassetta.info/material-library/ or by checking in this blog http://blenderaddonlist.blogspot.ch/search/label/Material
Those lookm great but what I want is a add on that I can jsut edit any material I want and keep track of them easily in a list without having to look for the object they are linked to. I might just have to make one myself. I have a feeling others need it, as well.
