A command, such as "/effect [name] none", would really be beneficial. When playing around with the effects I put in so many for so long that they don't even show a ticking timer (I assume that means in hours) and I am getting really annoyed with some of them and it won't let any more take effect. I can't go through and tediously take each one off by /effect and etc, because I don't know the amplifier I put on each. This would also really help server admins, who might want to take a status off of a player after an activity or testing something. The only thing that I can see bad coming of this would be people doing it and taking off others statuses while they are using them.
