Well you can change the function to your liking, so for example results ze each one after the other. Depends where you out the resize

When i think about it, it should actually resize each layer one by one. At least if you out the code like you wrote. Since its using [i] per layer. Dont understand why it would resize them all at once. My only guess is that it also resize the artlayergroup at the end. It would need some extra code it guess

One thing, the script's name isnt correct I believe. SInce this groups layers, why not name accordingly. PS why is that undo() in that loop?

My opinion, the main idea of this script is get the child layer, after grouping. He collect the child layer by that group (doc.activeLayer.layers), after collecting, he undo back to ungroup.

@no
I think this resize all items at once and the undoes the grouping.
