For a long time now, several people have voiced opinions on wanting to have layer groups in the After Effects Timeline. We even covered it a while back and included a mockup of how it might work. Well, the good people of Goodmotion—pun intended—have just previewed something they’ve been working on: GM FoldLayers.
This plugin appears to intelligently hide/reveal and color layers as a group using Nulls named with a ‘|’ prefix. Take a look at the video (only on Facebook at the time). The best part is this will be a free download. Someone please buy these people beers… lots of them; they deserve it.
