Add columns to view, like Category and Follow up flag (custom flag text)
Please allow users to add their own columns to their view. Most interested in Categories and Follow Up Flag (for the custom Flag to text).
Please make the follow-up flag opaque again. It's no longer stands out.
Please add the Outlook standard feature to allow flag-for follow up after sending while composing e-mails. To achieve this currently, you will need to set the flag on an e-mail after sending in the sent items folder.
