The vertical scroll bar is very thin and not easy to see or click on. Make it more like a regular Windows slider that is permanently visible.

Configure font size

In Skype, we have a very handful feature that allow us to right-click then choose "Quote" to get a message to be quoted in chat-box.
I think it would be nice if we could have it on Teams.

If you click on a teams, you should land directly on the first channel.
There should be a breadcrumb navigation for the channels in the teams, which can be optionally displayed between teams name and tabs.

Add Microsoft whiteboard in a Teams channel

For vision impaired uses that use custom High Contrast Theming, the Teams apps does not correctly map to the colors. For example, left list uses the Disabled vs Selected colors. Microsoft should be fully committed to one standard for Theming; especially for High Contrast Theme. It is critical for the vision impaired.

Register a global hotkey for windows (e.g. Win + T) to open up a new chat window, without having the application active.

s4b has such a global hotkeys

and ability to Customize the hotkeys

Have the font color selection include fonts with better contrast levels from the background. On the standard white background (don't know about others as my company has disabled themes), colors other than black are extremely hard to read.

As other users have noted, please add more font size choices, particularly for Wiki page titles. They are barely distinguishable from subheadings.

Having multiple windows for each tchat

When working on Teams, and also in Office 365, you can't "Paste special". This is super annoying, and is stopping a lot my colleagues from using teams. Which defeats the purpose of us paying for it.

Please make it more clear you are in a group chat. There have been several times a user will say something in group chat and think they are in a private chat. A different color background and/or color font and/or icon to indicate a group chat.

Scrolling to zoom into an image is reversed to what it should be. This behavior is on both mouse wheels and on the magic trackpad for mac

When the side bar is on auto-hide (when window is sized to a smaller width), once a Team channel is clicked, the sidebar should auto-hide again.

Please add function where you can drag and drop Teams folders within one another

It would be nice if the "followed channel" notification was a different color than the "direct mention" indicator. since I can't tell the difference, i find myself heading over to teams just to see conversations that I'm probably not interested in, which ends up being bad context-switching for me

The ability to search any types of WIKI within teams. if there is just clear text, please provide a type of search for that within groups. I can search files and other items just fine, but not clear text within groups, or Wiki's. This makes it very hard to find material.

To align with Agile methodologies, which have four status options for "user stories"/tasks, add a fourth option in the Progress drop down menu on each Task. The fourth option could be customizable or could be fixed to either "In Review" or "On Hold." Either gets a similar point across.

The four options in Agile could be:
to-do
doing
in review
completed

When will this be added to the compose message textbox in the Teams / Channels area of the app? It currently only functions in Chats and I'm sure a lot of people that voted for that (https://microsoftteams.uservoice.com/forums/555103-public/suggestions/16932934-up-arrow-to-edit-last-message) meant a vote for Channels / Teams, too or maybe even more importantly.

I chat privately all day and am part of and/or owner of Teams channels as well. I really need to be able to open both a chat window and a Teams window simultaneously so that there is not the constant need for keystrokes to go back and forth. People even get confused and put an entry they meant to put into a channel into a private chat because they forget which window is open. Opening multiple windows will enable you to watch and respond simultaneously just like you have email open all the time.
