Frequently, I find that I need to copy and paste HTML from another source into the HTML editor (as opposed to the rich-text editor) in the "classic" quiz engine, or to modify the HTML in this view. However, it appears that Quizzes.Next lacks an HTML editor, which forces me to paste the HTML into the rich-text editor, reformat the text between the tags using the rich-text editor, and then delete the tags -- a very clicky, time-consuming process. It would be so much better if I could, as today, paste/edit the HTML in an HTML editor then just go back to the rich-text editor and see it rendered.
On a separate note, the rich-text editor has no blockquote feature. Working on English and literature courses, I use this frequently in the "classic" quizzes.
