In our current LMS (eFront, which btw on the total is a "spot on" for us in terms of the featuritis curve) a general "Report error" functionality is activated/deactivated on a lesson level. When activated, the result is, that the UI is populated/cluttered with small yellow triangles every here and there (as you are suggesting Tim) . The great thing is, that when the enduser activates a test, a yellow triangle is added for each question and as soon as the yellow triangle is called upon from a certain question, the PM sent to me has the question-specific link mentioned above... and that link is the CSF for a smooth loop. Furthermore, assuming that the students approach (enjoying movies, interactions, tests etc while proceeding) follows some kind of normal distribution curve I try to follow what the "eager beavers" send to me in real time. If I manage to act upon the provided feedback immediately (and it is a good investment to do so) the consequence is, that the "late followers" (activating the same test some time after the eager ones) therefore sees another - improved - version of the same test.
I installed Moodle 2.7.1 and exchanged the theme to Essentials.
Now, to conclude, I guess either...
- jot around with the used theme/ the "help-button-trick" as suggested above
- pass along some kind of RFC to the Moodle-developers
- and/or have a plugin manifactured
...will solve this for me (and Frankie Kam seems to be quite skilled thanks Hartmut: excellent reference / very useful walkthrough). German Valeros suggestion is a really quick-n-dirty one, however by default I use to scramble question order as well as answer-order + show the questions 1-by-1 which would place that txt-question somewhere random in the question order which will confuse more than solve the issue.
Based on the info in the thread so far: there is at least no obious-out-of-the-box-functionality which I have missed which is good to know.
