Add newlines to back side of card
Would like to be able to add more than one line of text on the back of a card so that I can enter a list of "acceptance test criteria" or info for what "done" means for this story, ... even to the point of having some template of information for every new card I make (this is probably a new suggestion in its own right).

I would agree. Even if the editor was able to select front or back, or even two editor windows if necessary.
I had the same thought until one day I discovered, purely by accident, that SHIFT+ENTER does what you want. Personally I think this is counter intuitive - SHIFT+ should be required (ESC would be better actually) to exit the view. ENTER traditionally means carriage return.
The real problem here is the total lack of user documentation.
