For us, we'd prefer a Copy Link action take users to an editable version of the page they're being linked to. I understand this might not be preferrable for everyone, but with the appropriate permissions in place, there really isn't any security concern here.

It would be nice if an administrator could choose whether Copy Link resulted in a mode=View or mode=Edit link.

For hard-coded applications, we do modify the hyperlink to records to include the &mode=edit ULR parameter.
