My idea was to break those tasks apart, so uploads would queue up and could be processed at your leisure and possibly by different officers.
Bingo. This is the planned implementation, though it's a tad bit in the future.
Your suggestion of "Remembering the Paths" is unfortunately not possible for security reasons, as entering a default path into an <input type=file> tag is blocked by the browsers. If, for example, One were to enter <input type=file value="C
Windows\Win.ini"> It would simply ignore the "value" attribute, and present you with a blank path.
