Unit or Buff Frame that allows cancelling buffs

[LBXZero]

I am seeking a UnitFrames mod or Buff Frame mod that has the code for cancelling buffs on my character. It seems most of the mods that involve the Buff Frames exclude the "click to cancel buff" ability. It is very useful when someone uses a 1 hour costume buff that can only be cancelled by clicking the buff, and that costume prevents casting and mount.
