Toggle Mainboard, Maybeboard, and Sideboard categories in Export

{"ops":[{"insert":"Right now if I want to export the deck I think my only options are to export everything in the deck, including the maybeboard and sideboard, but often I only want to export what is in the main deck. It would be a great feature add to be able to toggle on and off the sideboard and maybeboards for exporting. \n\nAdditionally, when selecting the custom category export option, it could be a way to only export certain categories like creatures, artifacts, lands, etc. only. \n\nThanks for all the great work!\n"}]}
