Maybe just try installing MultiQuickButton and test.
But i have read about other users installed QuickButton first and try, then uninstalled and test MultiQuickButton after that, but then there is a conflict and not working.
If tried already QB, then need a new flash of BH (or whatever you use) and then install MQB.
I guess no one have checked what the conflict is (they just done it the easy way and flash a fresh install).
