Saving large values seems to cause problems. It fails to update the key and can cause a loss of all of your local storage if the large value is the first in line to be saved. I'm guessing there is an overzealous timeout delay or something. It is handy for viewing the full value of a local storage key if it exceeds what is shown in the inspector though.

wrong date in download filename.

why '+ 1'?

Great for migration testing from one local storage structure to another. Very labour saving, thanks

Well done! :)
