Similar to the tag / genre exclusions, I'd love the option to remove stories that are below a provided file-size.
I usually prefer stories above 75kb, and find anything below 40kb far to small to connect with, but they tend to fill up the view of the site, requiring hunting, or sticking only to the category search.
For implementation, I suspect some may prefer the opposite for max size, and for min-size, it may be good to either not include "In Progress", or to provide a checkbox.
