It would be great if u could integrate teams into outlook. i mean the whole functionality of the 'teams app' could be a 'tab' in outlook.

Make it work like Excel (AND EVERY OTHER APP ON THE PLANET).

Because most cameras are located at the top of a laptop screen or a webcam sitting on top of a monitor, by moving the attendee pictures/videos to the top, your line of sight is closer to looking in the camera than when you are looking down at the bottom of the screen, giving a more natural appearance to the interaction.

It would be great if Teams had a lite UI Mode where all (most of) the beauty is switched off to favor performance and minimize resource needs.

The current Teams App on Windows 10 needs a lot of performance to render and to run in general. I need my CPU and my RAM for my development work! Not to run a stupid chat client!
Skype for Business was much reasonable in its resource needs therefore I favor still that utility instead of Teams!

Add ability in Teams to arrange contacts by online/offline status like Skype has.

Right now we have a bunch of Group and once you start adding names to it, they are pretty hard to identify which one is which. If I could change the Group Chat icon, it will be easier for me to identify this.

Please create a keyboard shortcut for the ability to navigate 'Back' and 'Forward' (instead of having to mouse click on the upper-left arrows).

Please give me an option to collapse or expand all Favorites

It's very difficult to tell if I'm replying to someone as part of a particular conversation in a group chat or directly to them in a private one. My teammates have the same issue, and it's led to us inadvertantly typing messages in the group chat that we didn't want some team members to see. One possible way to remedy this would be to use different background colors for group chats compared to private ones

Add a static hyperlink in chat to jump to the Last Read section similar to the hyperlink to view new messages.

When using Skype for Business, participants were able to choose between "gallery view" or having in full-screen the participan that is talking at each moment

I'm not able to find that option in Teams, only gallery view or pinning manually one of the video signals as main and full-screen.

is this planned?

Would like to see the ability to undock the "Chat" function in the Teams window - like the Skype for Business interface, so that I can work in "Teams" and view documents while answering questions for folks. Too often, someone asks me a question, to answer it I have to leave the chat and find the document and then go back to the chat and then re-find the document. I also may want the chat up and visible while I'm working in other applications without wanting the heavier/larger total Teams UI on top.

Open Chat windows separately. This is very poor implementation of chat in MS TEAMS, as all proper communication tools that exist in the market have this feature. It allows for multiple chats to be viewed simultaneously. When is MS TEAMS dev team going to fix this glaring gap?

I am using the Windows Team application and sometimes I can't tell if I am looking at the offline information or online information until I click on several tabs and channel to prompt me to sign in. Please create a refresh button so we can make sure we are logged in.

Although markdown works as you type things in by hand, it should also format text that is pasted into Teams.

We often have markdown docs or other existing assets that we're discussing, and being able to copy-paste markdown into Teams would help make that process a lot easier than retyping everything by hand!
