I too would like to see the ability to add a reminder in the Outlook Add on. Currently I clip, then have to find my clipping in Evernote and then set a reminder, quite cumbersome.
I would love to see this feature also. Adding a reminder at the time the e-mail is clipped would be really useful for me. Currently after I've clipped my emails in Outlook I then have to go to Evernote and add reminders.
