And since my worst student ever will be back with me this Fall, [I'd like] the ability to mute folks as needed. The class [h]as no need for disrespectful, rude, snide comments!
I think this merits its own post. When I started teaching, I was too socialized about being "nice" and thus let a number of classes get dominated by disrespectful students. Eighteen years in, I now let the little dears know who's boss immediately. It really helps.
