Impossible to copy/past item+automation item at once
I select 1 item and 1 automation item.
I drag&drop with Ctrl pressed and there is only one of theme which is pasted.
Same issue with CTRL+C and CTRL+V.
Mouse modifier : left drag - copy automation item/item.
It's normal if you can past both when you drag & drop the media item because automation item under it will follow it with "envelope points move with media item".
Try to do the same thing by pulling the automation item. I think than you will not be able to past the media item despite the fact than mouse modifier for the midi item and the item are configured to copy/past with CTRL.
