I'll vote for that. Sometimes it's a wee bit hard to tell whether I am 
in a subscript/superscript, or in the "owner" of the 
subscript/superscript, or what. For example, if you enter $\sum_1^n$ and 
then mouse between the subscript, the superscript and the summation 
sign, the corners never change. If we could change the background for 
just the "relevant portion" (say, the portion subject to destruction if 
I hit the backspace key), that would be helpful. Right now, if I have 
the cursor just past the summation and hit backspace, it highlights the 
whole thing, conveniently telling me the amount of destruction I am 
about to unleash; but if the cursor is somewhere within the summation, 
backspacing does no highlighting or warning and just destroys something. 
(This is on 2.3.6.) Somewhat unexpectedly, if the cursor is just to the 
left of the sigma, backspacing nukes both subscript and superscript but 
leaves the sigma.
