I'd like to see a little window at the top of the Material tab that shows the name of the parent material from which the tweaked material was derived. We often start with a stock (or other) material and tweak for a client color, or scaled texture, then rename it and save it to a client folder. But it would be nice to know "from whence it came", so we can start over if necessary.
Also, PLEASE, a reset button that undoes all changes!
