A simple mod made in a couple of hours displays your damage per hit, along with a history of your last five hits that disappear after a few seconds of inactivity. You can open the interface settings by pressing the zero/0 key. Left-clicking on an interface element allows you to drag it, and right-clicking on an element allows you to change the color scheme, of which there aren't many.
There likely won't be any updates to the mod.
