Some others have asked me to allow writing html, in order to improve the reading of some comments, where there is a large text (default value is 400 chars), but html is not allowed. I tried to use Xinha as comment editor.

I'd like to know if does it make sense to have "enhance comments" on evaluation package.

On the other hand, some teachers have tried to publish not only a generic solution but a specific one to each student answer. So they are using comments this way, but... Does it make sense to allow teachers uploading a "correction" file?

If you eventually contribute this back, please take into account that, in term of accessibility, pop-ups are not recommended and xinha can't be used but this one can be turned off.

If you can't avoid using pop-ups, this article may help to do it as accessible as possible: http://www.alistapart.com/articles/popuplinks
