I'm usually a pretty big supporter but I have to vent on this latest Beta and the UI changes that accompanied this latest version, seemingly unannounced and completely unexplained.

As a System Administrator, one of the things I did ALL THE TIME was to go Manage -> Domains -> Choose a Domain -> then click the "Manage" button, choose which user, then impersonate on that domain with that user.  It was helpful to have the super-admin access to the data while impersonating as that user.  That's gone.  In fact, the "Manage" button when looking at the domain is gone - replaced with a whole bunch of tabs that show some information, but not as much as there used to be.  My entire workflow that I did ALL THE TIME is gone - not replaced with something better; just gone.

The new mailing lists administration changes make no sense.  The old ones didn't either but we had created our own well-written documentation to our large user base showing them how everything was setup and how it all fit together.  With one fell swoop all of our documentation that we had to write because the old setup process wasn't good has been made useless in favour of a new way of managing mailing lists which is even worse.  I can't imagine any real-world users tested this workflow.

I can go on but I'm just incredibly frustrated by this version having significant changes to the UI and yet there are STILL BUGS that didn't get fixed or addressed.  The priorities astound me.
