[http//en.wikipedia.org/wiki File:Editing_a_formula_using_VisualEditor.png This screenshot shows the formula ''E'' = ''mc2'' being edited using VisualEditor. The visual editor shows a button that allows to choose one of three offered modes to display a formula.]

I suggest a Math Editor, a full visual editor for VisualEditor. This would work in a similar way to a calculator. If you put / in the visual box in your keyboard, it would put the wikitext: \frac . It also can link to a visual list with commons functions (as square root), mathematical input graphical environment or math handwriting recognition [https://www.texthelp.com/en-us/products/equatio/equatio-for-windows/=]. Just an idea ;-)
