One feature I'd personally love to see on Deckstats would be the ability to keep a decklist from showing up on my user profile or the front page, but still allow anyone I send the link to view the list. Sometimes I want feedback from a specific person without spoiling the surprise for the rest of my playgroup, and the only way I've found to manage that is either copy the deck to an unsaved list or make it public temporarily and change it back.
