Why does Home now have its own sidebar that includes Spaces, Chats, All Tasks etc., but then those same locations/menus are repeated in the main sidebar RIGHT BESIDE the Home sidebar? Home needs to be more focused. Why would I want All Spaces and All Tasks listed in my curated Home page? I should the focused Home to the broader Spaces/Everything to access outside information.

This new UI is going to be super confusing for my older users that want one straightforward way to access each item and don't want to have to customize three different menus to get a working layout. The default interface needs to be WAAYYYY simpler. It was still confusing me after a day, and I'm good with software navigation.
