Would it be possible to add a command to cancel a buff by name, like: /cancelbuff "Blood for Blood"? It can be really hard to right-click buffs to turn them off if other buffs are falling or being applied at the same time, and it can be important to take Blood for Blood off before big damage. Obviously this can be worked around by not using it in the first place if big damage is going to happen within the buff duration, but since the feature is there to cancel the buff already, why not make it a little easier to use?
