This is just an addition enabling questions to be grouped by "difficulty" in addition to "category". At this time there are four possible difficulty settings: undefined, easy, medium, and hard.
It's really all very straightforward, and here are some partial screenshots to get a taste of how it works:
Screenshot #1: Question drop-down menu filters. Here you can see the extra dropdown menu which helps you to filter the questions by difficulty. It's completely independent from the Category menu.
Screenshot #2: Difficulty selector when creating/editing questions. This one is taken from the "create multiple questions" screen just to show that it also works with RANDOM questions (make me 10 random hard questions, please), but it's present in all the normal question types too. Default value is undefined, if the teacher can be bothered he can set it to whatever he wants.
Screenshot #3: Extra field in the questions-by-category list where you have the questions available for inclusion in your quiz. It shows the difficulty, the pictures are small icons (thus customizable) and there are tooltips. Image is hyperlinked to the "edit question" screen. It's obvious I copied all of this from the "Type" field.
Screenshot #4: The equivalent of #3 but in the quiz questions list. So you are able to see what your quiz includes.
What do you all think about this? Do you find it useful? Maybe useful enough to bug Martin about including it in the Moodle source?
Any suggestions anyone?
