I suggest alternatively to the [[]], we should use the same syntax for card lists as tappedout.net:
So the following:
1x Baloth Woodcrasher
1x Coral Merfolk
7x Forest
2x Frontier Guide
would be converted into links which show the card's image if hovered over and redirect to the gatherer or magiccards.info if clicked on. Therefore, copy&pasting of decks/combos form tappedout.net would be very convenient. Btw, Where does one have to request such a feature? How to reach the creators of this site?
Maybe the visual experience for this can be toggled on the layout: show the normal full card image or the behavior I described above. This would also reduce the bandwidth used for users which know the cards by their name and don't necessary need an image of it.
