How to access messaging plugin within Site pages

How to access messaging plugin within Site pages.
Currently messaging plugin options like inbox , sent items links take us to the wp-admin section.

I want to have these options as part of site pages, so that user do not move out of the current look and feel.

How to get messaging options (i.e : wp-admin/admin.php?page=messaging) in pages.

Or is it preferable to change look and feel of wp-admin section to sites look and feel ?

Looking forward to your suggestions
