Performance has been and continues to be a big focus area for Teams. One main area we have made improvements in is responsiveness for the most frequent user actions of switching between Chat, Channel, and Activity. We are also focused on reducing resource consumption and application load time. More improvements are on the way.

This is my one concern as Teams moves closer to convergence with Skype for Business. All versions of Skype are huge and bloated, and Teams already struggles with bloat. The biggest pain since moving from Slack has been performance. It's currently usable, but not really optimal. Please make this a priority.
This feature request is still being worked upon.
I am still trying to get details on what we could expect for Cortana in Teams and will share examples once something is available.
This item is still under review. I’ll keep following up with the feature team and sharing all your feedback.
We’re updating our command library all the time, so keep checking the menu in the command box to see what’s new by typing / or @.
As stated in the last update, the ability to use multiple Teams accounts at the same time is being implemented in stages for Desktop. Faster tenant switching functionality on the Windows client has been rolled out to the public ring fully, and Mac will begin rolling out soon. Work is in progress on cross-tenant notification improvements, and support for multiple accounts on desktop will follow. We’ll keep you posted!
Note: The ability to use multiple Teams accounts at the same time is supported on iOS & Android today.
