I would like to be able to use a date for the "show topics" selection on the Forum Updates gadget.

We don't have many posts and most of the ones we do have are old. Right now we have no way to limit what is shown based on a date and our home page (where the Forum Updates gadget is located) looks out-of-date.
Currently we can choose how many topics we'd like to show but I would like to be able to select "show topics newer than xx/xx/xxxx"
