Try this on for size. I know we have the personal nodelet, and it's great for what it does. But what about a way to flag a post as "clear-flag proof." In other words, when you hit the "I've Checked These!" button the flagged posts stay visible on "Newest Nodes." I envision a checkbox on the post pages and again on the newest nodes page.
Not knowing how the database is setup, I can imagine this will be a pain in the hat. :-) Please trout me if someone has already suggested it, but I could not find anything using the Super Search!
