Hi there, I think the duplicate structure should respect the end setting of the layer (if it´s on loop, hold, etc). and add the "duplicate" in the end. why? because I think it´s more usefull for an organizated project. I´m always put first the name of the character in order to have all the layers organizated, for example:

Lenno lines
Lenno shadows
Lenno color
Lenno alpha

when I duplicate a layer I always need to change the name and delete the first part. Am I the only one?

You can make a New Layer Preset with these settings and it should do what you intend. Just go to Layer > Open New Layer Presets. Then you can call it in the dropdown whenever you need to duplicate a layer and it should have the settings that you want.

thank you very very much!!!!
