[IxDA Discuss] select exact number widget?

[josh]

I don't recall seeing a widget that does this 'exactly' however your
conceptual example makes me think of something like to filling up "slots" or
a "basket"

Where people choose between a number of options and can move them into
bounded selection queue (the slots).
Some FTP clients or Install applications have a widget with two panes where
you a set of options on the left and you add them to the right. Sometimes
this is visualized by left and right arrows in between the two panes.  If
you have an option on the right you use the left arrow to remove it and add
it back to the right.

Picassa and other apps have a "tray" that act like a selection queue.
