Hi Mark,
The link will be to a custom admin page, which changes settings in relation to the course. So it is for a single instance, rather than site-wide.
I could put it in edit_form.php, but that would mean users would first have to go to the Configure... option and then click through.
I wanted to know whether it is possible to add another option to the drop-down, in addition to Configure..., Permissions, etc, with its own icon that could link to my custom admin page. Do you know if this is supported? Thanks.
