Yes.  After editing the source I would like to see a hint of how things would 
look like, and also
to make it easy for me to follow the latex code itself.  I also use it in 
conjunction with prettify-symbols.

For instance, consider

{\begin{aligned}
\langle \psi _{{jk}},\psi _{{lm}}\rangle 
&=  \int _{{-\infty }}^{\infty }\psi _{{jk}}(x)\overline {\psi _{{lm}}(x)}dx\\
&= \delta _{{jl}}\delta _{{km}}
\end{aligned}}
 
I would not like to have the  _  and  {}  showing in  the expression  \psi_{jk}

In industrial applications, equations are customarily very terse' with lot of 
spaces wasted printing  _  ^   {  }
 
Where the font change and height placement make it obvious whether something is 
superscript or subscript,
and what things are being grouped together with  {}.
