Window stays open after large file appears to be finished uploading

This is a great module. Thanks!

It would be a nice addition to add some text to the upload window that tells users that the window will close automatically once the file upload is complete. Otherwise, users uploading larger files may close the window and halt the upload before it is completed.

Example: When uploading a large file, the upload status gets to 100% and the progress meter is fully green, but then nothing happens right away. There is a delay. The status says "Uploaded 0/1 files" and just hangs there for an additional 10-15 seconds for my test file of 24 MB. Then, the window disappears and the file appears in the list.

However, the first 3 tests of this module, I clicked the "Close" button after seeing the status of 100% and yet my file didn't appear in the folder because it wasn't completely finished uploading. Once I waited for the window to close itself the file appeared successfully in the folder.
