The discussion here motivated me to share a script I made to simplify work on my own iconset. It lets you extract and rename all icons at the click of a button plus gives you an html page as a reference.
@skinz I absolutely love your icons, especially the dualtone ones. Sure, it may be a case of "form over function" since more colors often make for faster recognition, but the minimalist look is just great! Thanks for sharing!!
(BTW I found a small error in FLUENT_UI26_THIN.xml: The filename in the second set is missing the ".png" extension.)
