First I have searched for this topic and have not found it, so I figured I would make a post about it.
Just like title says, the anti drag option would be exactly what is on runelite for osrs. You simple toggle the option on and when you are fletching it wont drag the dart tips/feathers. So essentially when you are fletching darts you can toggle an option to where when you click on darts and the feathers or vise versa it wont drag the darts/feathers when you are going fast. It will make fletching large amounts of dart's less aids.
Thank you for looking and possibly considering my idea,
