I noticed that when the user drags the cards around too quickly, this app drops them.
I went to a few published apps, such as 1010, which involve dragging things, and I noticed that a good, polished app does not drop anything.
how would you correct your code so that no matter how fast the user drags, if they don’t lift up their finger, the card will stick to that finger forever?
your app supports multi-touch gestures, maybe by accident… how would you make the cards stick to each of the user’s fingers, in the case that a multitouch drag gesture was underway?
