- Bug fix: List was not resizing correctly when showing the keyboard, so some list items were hidden behind the keyboard. - Bug fix: List was resizing when it shouldn't have after tapping the Reorder button.

- Added ability to move items from one list to another. - Enhancement to the Reorder functionality. - Resolved a bug where after having selected an item, then performed a reorder, and then changed the item text, it would update the text of the wrong item in the list but in the database it updated the correct one, not causing. Reloading the list would then show the correct list items.
