Contact list no longer available in new Teams version

I will add my voice to this thread. I found small area of "Contact List" and the Contact Groups within it a (clunky) workaround for handling multiple department contacts. The obscenely HUGE (and frankly pointless) history display in the same window was just salt in the wound.

I hoped a better user experience would be available in "new" Teams, but it seems what little that made it bearable has been removed (in classic Microsoft fashion). I reverted within 2 minutes of trying the "new" version.

The ability to group contacts makes a nasty UI a bit better to use. Losing it seems counter-intuitive to anything approaching a smooth workflow for anyone with multiple contacts in multiple departments.
