It seems like the wiki content is not searchable with the global search

A wiki you cannot search for entries is useless...

When renaming a Team Channel, the associated Sharepoint folder continues with it's previous name. This could lead to confusion.

Add a whiteboard to share.

Slack has this: get.slack.help/hc/en-us/articles/206870317-..

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.

Would like to create a Public/announcements Read Only channel so that only specified members can post. This allows for authorized personnel to make company announcements, but not everyone can post.

(The request for a Public Announcement channel is complete, since the General channel can be controlled by admins and set to read only)

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

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.

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.

Use Windows 10 notification center for notifications

Every time you create a task in planner via Microsoft Teams and assign it to someone in your organisation/team it would be nice to see that task in outlook as well. I want to know and to be alerted that I have a task assigned to me without having to lon on to Microsoft Teams.
It would be great to have a place to see how many tasks have been created in a team/channel and the status of each one.

Slash commands for just about every type of function are a must have. They are familiar and easy to use without having to touch your mouse, they are UI-agnostic. Admittedly not terribly discoverable – but the UI is even worse, as their is no real option for auto-completion of UI elements, now is there?

Notifications built into the OS (which all apps I've seen use other than Outlook and now Teams) are more functional and allow for more user control. Most importantly, they honor Do Not Disturb settings, which is critical.

Make it so we can change the name of the General Channel.

Right now there is a unread message count badge on the Activity tab icon (I guess you only get that if you have followed any channels?). However I would much rather prefer if the badge was on the Chat and Teams tab icons so I can see where there is activity. Currently collapsed teams are also indicated having activity. Expanded teams should have the same indication.

Furthermore, the unread activity badge on both the Activity and the application icon count unread channels. I would prefer a message count.

Planner and Teams just needs a notification - when a task has been created for an assigned user that user should receive a notification - currently we are doing a work around by starting a conversation with a mention of a member name
thanks

It would be nice to integrate public Skype (not Skype for Business) into Teams. I am able to chat with Skype for business users within my organization but when working with external clients I still have to go back to public Skype. If I could even just simply chat and call with Skype users as well that would allow me to use Teams as my sole communication platform.
