When working on websites we often have breakout's with a ton of iterations for single pages/tools in pages.

Currently I just put all the iterations in the same XD file, but the file is now huge and takes several minutes to open.

It would be extremely useful to take the an artboard and make a whole new document from the selected artboard. There doesn't need to be any linking between artboards, simply taking that single artboard and creating a new document with the same color palette and objects.

A workaround is copying all the artboard contents and pasting into a new document, but unfortunately this doesn't keep the objects or color palette.
