How to link "Logged-in users" in the backend to CB profile ?

Hello,

my question is mostly in the subject of this post

When I click on one of the "Last 5 Logged-in Users" in
the dedicated area in the backend, then I reach to the
core joomal "User Manager:","Edit User" section.

Could I change that to reach to the user CB profile ?

This issue is not "urgent" to me, however if I could
clean the setting to avoid anyone using the core user
editor, that would be cleaner.

Thanks

Probably not without editing Joomla or maybe a system plugin to redirect. You could try adjusting the permission for your other admins though. Navigate to Users > User Manager > Options > Permissions and set "Access Administration Interface" to "Denied" for your other managers, but I can't recall if this'll block them from CBs as well or not so be sure to test thoroughly.
