Mathematics tools

Now I have DragMath working as can be seen in the screen shot. When editing the short-answer question as teacher, the DM extension worked fine. But as you can see in the picture there is no HTML editor for the students answer field (at least not in my 1.8.2).

The short-answer question didn't have any problem recognizing a proper Moodle TeX expression as right. So that seems promising!

Some questions I have:

How is the documentation/help page to be displayed (I don't see any (?)s)

Is there any possibility of getting the [_] outline display to work?

(Another TeX question I have is that I have been bothered for a while with a bunch of text before each TeX equation:
I have now been able to get rid of it on the filter administration page, after some hesitation, because of the warning not to change anything! I certainly didn't put it there. Anyone else had that problem?)
