How do I tell if cards are stacked on top of each other?
there seems to be no indicator.
A slight shadow will be created when cards are stacked on top of one another. It does take a quite a few cards before the shadow to become obvious so there opportunity for revision. Another idea we’ve had has been to not let cards stack at all.
Since this request was submitted in 2013, please let me know if I can assist you in setting up a new trial of cardboardit.com. A lot has changed in the past three years, and I’d like your input in the cards stacking and overall new feel.

I think the shadow of the card gets darker and darker as more cards are layered on top. Three makes it black. Removing the cards is a bit odd. I found if I drag them off, sometimes they disappear, other times they land where I drag them. If I delete them (why the X card at the top), other cards that I thought I had deleted somehow appear. This seems a bit buggy to me.

it appears that the border changes slightly on the top card, would be helpful if it was more distinct and/or explicit - ex: a number in the corner of the top card indicating the number of cards below it
