I've been working on the Got_It
icons in the past few weeks. Many of the icons were 32x exports made from 48px-optimized SVGs. I've been going through re-exporting and correcting anything else by hand as well as making a few new icons here and there. It's really cleaned up the interface.

Edit: Had to remove an icon but updated the newer revision to 239 (from 205).
