Yes, I think that there's a limit to 100 KB per e-mail, though I'm  
surprised that the screenshot is as big as it is.

This is definitely the case. I think anyone not familiar with the  
implementation would not be able to tell the difference between the new  
options.

This sounds like a good idea. The ZMI has traditionally suffered from just  
having more and more knobs to twiddle with little thought of the actual  
UI. I don't think that should block this PR (if it's required to solve a  
common problem at short notice).
