Often I see duplicate contacts (even when I have don't allow duplicates) and I just want to click one button, search my contacts and check all that apply to initiate the merge contacts.

This functionality would be a lot less cumbersome then having to back out, search the database for contact 1, then search for contact 2, then select bulk action dropdown. It would be nice to have a little button like below Payments notes, associations, etc. in the top right corner of the contact page opened view so I could search for duplicates. Or even under the "actions" tab that would be helpful to have merge duplicate.
