[wp-testers] Reasoning behind admin navigation?

[Bryan J. Harley]

What was the reasoning for removing "Dashboard," "Users," "Plugins,"
and "Settings" (Options) as tabs in the admin navigation?  I can't see
any design benefits.  Dashboard seems awkwardly placed at the very top
by itself.  As do the rest... justified right, a list with separators.
 Why aren't they tabs anymore?   Such a change just adds confusion and
inconvenience.
