Photoshop Inspired Layer Comps in After Effects (After Effects Layers Sets)

It would help my workflows to have Photoshop inspired Layer Comps in After Effects.  To avoid confustion with Compositions, perhaps this could be called After Effects Layer Sets.

As a designer, I often create muliple design compositions of a layout to show clients.  Using layer comps (or layer sets) I could create, manage and view multiple versions of a layout in a single Composition.

A layer set would be a snapshop of a state of Layers in the Composition, recording Layer visibility.  Since time is also a component, Layer Sets could also record the location of the Current Time Indicator and the location of the Work Area Begin and Work Area End.

Here is how it works in Photoshop: https://helpx.adobe.com/photoshop/using/layer-comps.html

I currently make use of Layer Color Labels and duplicate Compositions to do this.  Layer Sets would allow for versioning more easily in the same composition.
