I want to have a bank of images at the bottom of the app. At
the top, a title list. I want to manage a deck like this so that
you can drop images from the data grid to the title list and send
it to the server as a deck. I then want the ability to drag
existing images back to the data grid to remove them from the deck.
I also want to be able to drag directly into the data grid to
upload to the library. How can I do these things?
