I used to be able to drag a contact (or a number of contacts) from one group to another in the group view window in ACT6. This would add the contact to another group (adds new group membership to that contact) i.e. copy.
That functuality doesn't appear in ACT11.
I would also like to be able to drag a contact (or a number of contacts) to move it from one group to another (i.e. change it's membership).
Clicking on 'Add/Remove contacts link in the group view and then searching for contacts to add/remove is so time-consuming.
