It is annoying to have to click on the “New Messages” button or scroll down manually when new messages arrive. The suggestion here is to keep scrolling down to bottom and to provide a button to jump back to last unread message.

Allow clickable links on #hashtagged items ... in a channel or group, perform a search within that group.

For DMs and conversations, search all of your conversations

The "reply" button is WAY too large under each message. I recommend either making the button just a smaller icon and off to the side of a message, or only showing it on hover.

It's very confusing to new users that there is a difference between replying to an existing conversation and starting a new one within a channel. This is a visual thing as much as anything else. The 'reply' buttons are not naturally attractive if you just want to start typing a message. There should be a logical gap between the bottom of a conversation and 'start a new conversation'. 'Start a new conversation' needs to be separated visually, as if it's a second order command rather than a first order...reply.

Mobile working, Asynchronous working of teams is a common phenomena. Read receipts let us know if the message has been seen, so we know it can be acted on. Critical when large numbers of the team are mainly mobile workers.

Guys, please add pinned items for channels. We often pin important articles/messages/files so that the whole team can see it. Very important!

While there's an indication of the user that's actively typing in the Chat area, I'd like to have this in the Teams area as well

We would like to use group chats for conversations that are not team/work related. However, the 20 participant limit keeps us from using the feature to it's full extent. Please increase the participant limit for group chats from 20 to 100.

Once a person is added to a group chat. You cannot remove them. You must create a new chat and lose all the history.

Can Teams chat and activities data be exported, printed, archived, and backed up/restored? Within Sharepoint or elsewhere? This could be necessary for a few reasons both during projects and for historical records.

IMPROVE actual markdown:

Disable auto-formatting of markdown
*italic* not *bold* or _italic_
Make it the SAME as GITHUB
https://guides.github.com/features/mastering-markdown/
which is closer to DaringFireball
http://daringfireball.net/projects/markdown/

IMPROVE for mobile:
Please add markdown support for Android client.

IMPROVE for other languages:
Currently the code formatting doesn't work for german keyboard users due to the system expecting another character after the `
Due to that, Teams does not recognize the ` and interprets it as any other character.
I think that needs to change.

If you paste a link it should embed the media right in the chat (Gif, mp4, youtube, Vimeo, Soundcloud etc.)

I was surprised that conversations within Teams doesn't show up inside the conversation thread in Outlook Groups. Please consider at least connecting the "General" channel with the Outlook Conversation.

Current when @Tagging someone you have to type @PartOfTheirName then wait for the dialog to pop up, then hit tab or enter click the desired name (Person, Channel, Team). If you fail to use the dialog the @Tag fails to work even if you match the name perfectly.

What we'd like to see is typing @Name or @ChannelName or @TeamName just works even without using the dialog.

Since a lot of people type messages in quick succession, it'd be helpful to have the ability to drag and merge them together into individual "reply threads".

Currently, it's not possible to select & copy more than one message in a chat. When I try to select two or more messages, the focus stays on the first message making it impossible to copy whole chat.

There are some really ugly workarounds like: https://techcommunity.microsoft.com/t5/Microsoft-Teams/Copying-conversations/td-p/62849 which I don't consider a solution of the situation.

I want to be able to select multiple messages at once and copy them by hitting CTRL+C.
