Outlook reading pane has been usurped by TD
Tried TD with Outlook, but had to uninstall after realize that TD had usurped reading pane on the right side of the screen. It would be practical and useful if these two views can be toggled (reading pane and TD).
The menu for your Projects and other views is a drop-down menu with the Outlook plugin. You can click on the "Show Menu" button at the top left side.
We might consider allowing this to be the full view in future updates, though it would then take up quite a bit of space for the rest of Outlook.
