What about encouraging people to leave their LW running with a "while away" sub-menu for the "Repeat Search"?

Better yet, I'd like LW to automatically re-search for the key terms of inactive downloads "while away."

this option would become available in the downloads pane (rather than reactivating overly broad queries) . . .

--if it had been active at least once (i.e--there is a source out there that has been manually found and initiated by the user)

--if there has been no keyboard or mouse action for 1 or 2 hours. (allows refreshing downloads overnight or while at work).

Would a limited automatic search once every 1 or 2 hours from an otherwise inactive machine be harmful or easily abused?
