I haven’t really seen this discussed yet, but I have been using it a LOT lately. [info here] It makes revisions so much less painful. I know go through 2-3 times as many iterations in a shorter period of time now, and am able to keep my files managed much more efficiently than before. As long as this can handle larger files (svgs with embedded images), then its even better than a plugin to me! Well done!
I’m not sure if anyone else has made much use of this feature, but I know I have, and its worth checking out. I know it says it only works on up to AI 2015, but I have had great success in the latest version of AI CC.
