As the topic. A layer can be copied (added), but not delete.

Maybe a layer rename node is also needed.

It's useful when I just copy a layer, do something with it, and then I dont want the layer anymore.

Hi,

You can simply use a blast or a delete node.
The group drop down should allow you to choose which layer you want to delete.
(which ends up adding @name=layername in the group param)
