@dae Thanks! I noticed that the first time I clicked “Toggle MathJax Rendering,” nothing happened, but from then on it correctly toggled (I haven’t been able to reproduce it). Also, I think the settings gear
would be a more logical place to put the toggle option. Perhaps also display a checkbox as is the case for “Shrink Images” so that users can see what the current setting is
Edit: Moved problems relating to toggling the MathJax rendering to a new post here: Anki 2.1.55 Beta, MathJax Preview
