The current \(a^nb^n\) is actually displayed as \(a^{nbn}\) which is misleading. This is what bothered me first. OTOH, I have set up preview of formulas (actually I did it for tikz diagrams) and it works well. It is slower, and I use it for complicated formulas only, but at least it is exact. Fabrice
