Remove $

Is it possible to remove the dollar sign from the formulas produced by mlb?

Do you mean that you want to hide dollar signs for inline maths like $\infty$ ?
It's possible, but I think it makes less intuitive when editing formulas directly within a magic-latex buffer, since it's not clear 1. how to delete the hidden dollar sign and 2. whether to insert new characters inside of formulas or not when the user type something at the edge of formulas.

I understand your point. Anyway I believe that it would be really nicer and more clear. This is what happen for example with org mode preview latex fragments.
