Currently the deckbuilder can't open decks in Shandalar format, and editing Shandalar decks requires putting a deck together then manually copy-pasting it's contents into a properly formated deck in a folder separate from the one used by the deckbuilder (and there's the whole unintuitive naming scheme, too).

You said you could enable the deckbuilder to edit shandalar decks directly, to remind you with a formal request, so here it is.
