True - neither of us is perfect, but I don't think I ever intimated that on either front - only one of us has the ability to close Tracker tickets though, so I am assuming you are closer to perfection than I am
My issue is having ideas dismissed in the Tracker, like it appears 24814 was, given that is (from what I can tell) exactly the same thing I requested (i.e. manual forced submission), which you've accepted is not the same as what the quiz now does (i.e. automatic forced submission). I am all for discussing this constructively, I just get slightly disappointed when I get a sense that a "skim it, dismiss it, close it" mentality is applied to suggestions in the Tracker, rather than asking more questions to elicit responses from an end user first. I realise you and the other core developers are all extremely busy, but this is the kind of response that makes it very difficult for me to try and drum up community engagement in the tracker if contributors are going to get shut down as soon as they open their mouths.
Now, you're right, I didn't respond point by point, I was still clarifying whether there was any validity in my argument. Now it would appear that there may be, so I'll respond one by one:
"3. is covered by the Moodle 2.0 features, where you can have different open and close dates for different students." <- fair point, and provided I know what times I want the groups to close, then I can forward schedule this. If not, there is at least a workaround to go in and edit the settings to set each group to expire as I need to. I'm thinking there are probably more clicks needed to do it this way, but I accept that there is a work around.
"1. You can partly handle by editing the quiz settings to change the close date to Now. This will cause the quiz to submit the next time the student moves to another page, or submits one question." <- Again, acknowledged, however again I suspect it will be more clicks than a function like you discuss below, and from an end user's perspective perhaps not so intuitive.
"2. I just a bit crazy! There is a feature that could be implemented, but which has not been yet. In the quiz grades/responses report, you could have an option 'Submit in progress attempts now' next to 'regrade attempts' and 'delete attempts'. Making that button work would be quite easy. The tricky bit would be that if the teacher did that when the student has the quiz open, the next time the student does anything (navigates or submits a question) they will get a fatal error. We would have to detect that situation, and explain what is happening to the student, and I can't quite see how to do that." <- now we're getting somewhere. This is the kind of function I was thinking of, and the location of the button sounds good to me. Acknowledge that there would be caution needed in how it was implemented and used - are you willing to consider this further?
Finally, a little background (which perhaps I should have added originally), this was something which was raised to me as one of the most common requests that our Help Desk (supporting numerous Universities running Moodle) receive. The use cases were ones I came up with on the spur of the moment. I will ask them to comment on this ticket directly as to whether we're working towards something of use. As you no doubt also saw I tried to drum up some interest on Twitter for this issue, as I'd love to know if it is just something that our clients ask us for or if it is something on the broader wish-list for larger users.
Hope this gives some more context and detail,
