Whenever I open a large document (with preview on) and scroll through it for the first time it has to think to render the math preview. It would be nice if there were a "force preview" command to do this all at once and/or a preference option to do this automatically on opening. I rather wait once until it is ready than several times as I am trying to get to work.
Also there appears to be a bug. Sometimes when I edit an equation and pop out of math mode it reverts back to the previous view. If I click in and then out again it then renders properly. -Scott
