Thanks for getting engaged even at this very late stage guys.
As this is an MUA project (that they defined and funded) we're primarily engaging with them on this over at moodleassociation.org
Of course, feedback from all stakeholders is also welcome on the tracker, although, as usual, a bunch of opinions on user interface are very difficult to weight and synthesise there. This was one of the whole points of the MUA as a body, and our UX design process from some months ago, to help define the specs that we've been working to address.
The team are working hard now on addressing new issues being raised. Helen posted a good description of the phase we are in.
