Any extension/script to disable the whole wiggle thing that WK does?

Like when you hit enter accidentally before entering a reading, it wiggles… and when you mix up on/kun. Any extension (or could it be easily made by someone here?) that will do something else, maybe turn the input box yellow instead or something? 

Thanks all.

I don’t think anyone’s done it, but it doesn’t sound like something that would be difficult to script.  Not a bad idea, actually.
