Clear Recent Scripts

If there isn't a way to Clear Recent Scripts from the menu show below, then I would like to submit a feature request. I wish it would automatically delete (or not store) duplicates which just clutters things. This is like a fox chasing its tail, you don't know which duplicate is the right one, so you add another to be sure it's pointed to the right script. Maybe it should be clear unused scripts, but I will defer to Mr. Noodle's good sense.

Are you sure they are unused? When you hover over them, they should show you the full path. If they all have different paths then you should track down the other rules which are using them.
