The latest update now includes the 'Group By' views correctly, which is a great step forward for our implementation (as we use Group By extensively)

However, when looking at the views in harmon.ie, the group by 'headings' are displayed in their own column, and all the documents below show a 0 in this column.
This leaves you with a compromise - do you shrink the width of the headings (so that you can't really see them) so that you can view the filenames of the docuents, or do you leave the headings at a full width, and then have to scroll right to see the file names.

As this is designed as a 'sidebar' to Outlook, and therefore (in theory) designed to work ina relatively narrow width, this seems to be a poor design choice.

It could be partially alleviated by remove the title of the group by header from the title (it currently says 'Content Type:ICT Document' when it could just say 'ICT Document'

Is there anything I can do to my views that can alleviate this behaviour?

I've attached a screensh to show an example of my dliema.
