[Export layers to multiple files]

Export layers maintaining the document size and its position in it is a must for matte painters to be able to re-comp them into nuke. Keep us posted if there is updates! Thank you!

[duplicate document]

Yes!

I do very vey often duplicate a bunch of groups to a new document to then merge those into single layers and save a lightest/cleaner psd version of my working psb to send to client or comp into nuke.

Or even, when doing concept work I use the snapshot of the History tab frequently while testing quick stuff, then I can go back to previous states where I had something I liked, duplicate it into a new document and create versions, or drag it into the latest version I am on. 

Any way to reproduce those in AP?
