Bring back displaying the 'Flag' next to any Outlook folder in which exists any email that the user 'flagged.'
You had this capability before. It later disappeared. Display the 'Flag' next to each and every folder containing one or more 'flagged' emails. This is very helpful in alerting the Outlook user that 'flagged' emails may be 'hiding' in existing folders.

And please highlight the entire line item, not just the little flag in the corner.

Previously, customized colored flags could be added next to the small delete icon in the preview pane for each email. You could set these colored flags to correspond with any folder that you had created, and when you clicked on the flag that email would automatically be moved to the appropriate folder. This feature was very useful to sort emails into commonly used folders with one click.
