[feature] layer / group separation

[Lewiscowles1986]

Hey this is so cool, as is your infinite canvas tool tl-draw.

This feature request, may well be ignorance on my part, but when trying out the .com example, any change I made to settings was propagated to both past and future drawings. I Think the solve is adding another layer of indirection, to allow each shape to have an optional ref to settings for that specific drawing, rather than to all drawings.

Rather than manually doing this; I'm wondering if it's a feature you've considered, or have another way to support using what-is?
