This was started and usability tested as a Finnish Summer of Code project, and then Olli did further work on it in his own time to get it in shape for inclusion in Moodle 2.0. I reviewed all the code. There are a number of minor outstanding issues that will be fixed soon. See the subtasks of MDL-17284 for a list.
The goal of these changes is to:
* help teachers new to Moodle, so when they first see the quiz editing page, they don't go "Huh! What on earth am I supposed to do here?"
* help novice Moodle users understand and learn to use some of the more advanced quiz feature;
* but, without slowing down more experienced quiz users.
Naturally, with ambitous goals like that, we won't have managed to satisy everybody, but I think this change is a big step in the right direction.
There is extensive documentation on this project at http://docs.moodle.org/en/Development:Quiz_UI_redesign.
* New basic define roles mode, with just an Allow checkbox for each capability.
* Button to toggle this form to/from advanced mode.
* Also, a separate mode for viewing a role definition, rather than just showing disabled checkboxes.
* Now duplicating a role just takes to you a pre-populated add role form, so you can double-check things before saving the new role.
* Deleting a role is now logged.
* Role reordering code cleaned up.
* You can now no longer delete the last role that has admin permissions.
* This includes a general refactor of manage.php, which eliminates manage.html, and splits of define.php.
I have collected code that used to be in lib/adminlib.php, lib/accesslib.php and user/selector/lib.php into a new admin/roles/lib.php file.
And I added standard GPL and Moodle comments to all the files in admin/roles.
This implements the page showing the table. It is not yet integrated into the tab bar. To try this, go to an Assign roles page (one with URL .../admin/roles/assign.php?contextid=...) and change the 'assign' to 'explain'.
