Editor

Hello!

While working on Drag the Words or Fill in the blanks, I noticed that the editor is a bit too limited or not even there. I wanted to make two columns, so the layout was prettier. Eventually, I could make it work without it, too, but it would be way easier to just click and then have two columns. 

I tried to do it with codes (<>), but it didn't work either.

This is kind of a feature request, but I guess a developer discussion might help: I was asked whether I could allow setting the ALT tag for images in Image Juxtaposition. This would help to meet accessibility guidelines.
