I'm finding the current capabilities of list views a little stifling.
Since we currently only have the on "onAction" method to work with on a list it seems like all you can do with a list is use it as a starting point to drill down to a record for more detail.
It would be nice to perform somewhat more complicated actions. For example being able to see a list of "To Do Items" and click a check box and mark the item as completed, but still be able to tap the item in other areas to be able to drill down to a detail view. I believe in the jQuery Mobile UI world this is called a "split button list"
