Group and ungroup
Precomping can simplify a long list of layers in a single comp but creates multiple inaccessible comps. It is now possible for the first time in After Effects to precomp and un-precomp groups with a click.

Group layers are rectangle guide layers that do not render but can help transform multiple elements. Interacting with these is possible by switching layer visibility eyeball or adjusting the transform properties. Click to toggle all guild layer visibility with a click.
Delete all guide layers
If groups aren’t your thing and you end up with a bunch of unnecessary layers, click to remove all guide layers from the comp.
