This block looks very interesting but I don't have the ability to position it in the content region (like course overview) on a Standard theme on Moodle 2.2.
Is this a bug or have i missed a configuration step?
sounds like a bug - what page are you trying to add it to? - it's really only supported on the My Moodle page.
Only tried it on the My Home page.
Update. It's possible to move this to the content position using the move block icon. It's not possible to define the position in the block's congig page.
