I had a quick look and I love the improvements! It is more intuitive in my opinion. I like the clear overview of the streams (title, description, ID, your role) and the option to switch accounts.
Small suggestion might be to add a hyperlink at the bottom of the info tooltips which opens a relevant tutorial or page from the Speckle website. This enables new users to quickly jump to more information if they would like to. When I have time, I will do some more testing and think of other improvements.
