Nesting Layers

[PeacockK]

Hi @davicustodio - Excellent plugin here that really tidies up adding numerous layers!

I have a quick question, I've done a little bit of tinkering but to no avail, is it possible to nest groups, such that I can have a group within a group? I.E:

|Food
||Fruit
|||Bananas
> Banana Tree Marker Layer
> Banana Factory Marker Layer
|||Lemons
> Lemon Marker Layer
||Vegetables
||| Potatoes
> Potato Marker Layer
|Drinks
||Alcoholic
|||Vodka

Vodka Markers
||Non-Alcoholic

Appreciate this isn't so much an issue, but as said, can't seem to figure out how to nest groups - any help would be greatly appreciated.

Thanks,
Kris
