I think that if one of the options of showing Files list and Images list (or both) are enabled, the user will be able to choose if he wants his uploaded file(s) or image(s) appear on these lists.
Something like: [checkbox] Make this file private?
And in a tooltip or something similar will be said "If checked, the file won't be shown on the public files & images lists."
DFH is a very good script, I'm happy with it.
When 2.0.1 is released to the public?
