Damaging plus is an updated version of kronchev's Damaging. kronchev deserves all credit for the original concept. I have only expanded upon his work.
When in combat, Damaging Plus will display a frame indicating your ranged damage modifier. This is especially useful to marksman hunters who should reapply Serpent Sting when this number increases significantly. A threshold for an alarm (both visual and audible) can be set in the UI.
Commands:
/dmg show - Shows Damaging Plus (useful for positioning when not in combat).
/dmg hide - Hides Damaging Plus
/dmg lock - Locks Damaging Plus
/dmg unlock - Unlocks Damaging Plus
/dmg - Displays these commands
