I need some more functions

For books full of maths I need equation reference and more compatible LaTeX commands. There is an annoying bug in the “Edit Equation” window: when you type (apostrophe = prime) it turns into ’ (right single quotation mark) and the equation becomes invalid if you don’t type CMD+Z. I need also to insert “callouts” to the equations.
