Maybe I am missing something that is already there, but I agree with the sentiments here. I would like a way to select-all, unmark for export, there is way to much junk being exporting and it is way too time consuming to find it all and unmark it for export.

Agree with that,

This is a needed feature to be able to generate better design spec files for developers. Going through design iterations, and adding imagery, then duplicating boards for interaction workflows, you quickly keep adding unnecessary export files, and there should be an easier way to manage the export list, quickly unselect all and choose the right ones for final export to dev specs

I agree. Adding the ability to globally disable mark for export would be greatly desired.

A workspace to manage what has been marked for batch export and choose a file type would be very helpful.

Is there a way to unmark all marked elements for batch export. I find batch useful, for example, as a way to export elements from the repeat grid. But it already happened few times that I forgot to unmark an element and later I found that batch export included assets I did not need anymore. How to find what is selected for batch export? I need to manually search for items through all artboards right now. It would be useful to be able to unmark all elements selected for batch export.
