Excellent! Rated 5 out of 5 stars

Excellent and works very well. Have only a suggestion: it is difficult to edit an equation which has minor errors (one has to select the formula and to undo it repeatedly). Any improvements to this feature would make it even better.
An issue is that equations which do not give any error in LaTeX give some strange errors such as "Formula not parsed", while redoing it repeatedly usually is one way that I have been able to make the equations work!

This review is for a previous version of the add-on (1.2.1).
