Please give me an option to collapse or expand all Favorites

Allow upload a picture to change the Channel header background. Will help users to differentiate between channels.

I would like to see the answer call button for call be changed to green. This would highlight the action similar to the hang up button being red.

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

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?

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

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

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.

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

While I know we can reply to the top-level topic we can't reply to a post replying to this topic.

Currently I have to pull out each reply like this as a separate Topic which is cumbersome and loses the original context.

I 'simply' want to Reply to any Posts in Teams, be that a top-level topic or a response to that Topic, so that I can have a fully threaded, contextual conversation.

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!

Often, the <--Reply appears hidden behind the "Start a new conversation" field. This results in forking conversations rather than keeping all under a single topic thread.

Could the Reply button move out where we already expect to see Conversation tools?

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?

Please allow switching between default and dark theme automatically based on the dark mode setting in macOS system preferences.

In the Chat tab, my boss complains that he can't open Teams while in screen sharing applications (such as WebEx) because if he does then the last thing said to each of his contacts is visible and may compromise confidential info. He'd like the option to turn off the preview and only show the names of the people without any message preview.

In Slack I can see the members of a channel, but I also know at a glance how many people are in the channel. With Teams I can see the team members but it is hard to get a quantity. Also, I don't know how to see who is following a given channel in the team. If I have a dead channel I want to know so I can remove it.
