We are now preparing for the roll out of Tasks in Teams which will integrate additional features integrating To-Do and Planner. This includes additional list views that also extend to tabs in teams. Further announcements about additional integration in our overall Tasks coherence effort will follow.
You can follow the rollout via our Roadmap item: https://www.microsoft.com/microsoft-365/roadmap?searchterms=57213. To see a preview of the experience, please visit https://youtu.be/rTATVGroEsQ.
if you have an existing post that you want to show in a different channel, you can edit the message and cross-post. This will add the top-level post to the different channel, but will not include the full set of replies. We will keep this request in mind as we evolve the cross-posting feature in the future and update if the status changes.
Details on cross posting can be found here: https://support.office.com/article/cross-post-a-channel-conversation-in-teams-9c1252a3-67ef-498e-a7c1-dd7147b3d295.
Pinning the entire document library is supported today. Learn more here, https://support.microsoft.com/en-us/office/add-a-sharepoint-page-or-list-to-a-channel-in-teams-131edef1-455f-4c67-a8ce-efa2ebf25f0b.
We currently do not support pinning a specific folder, but we are considering this feature.
Thank you for your feedback. The feature team is currently working on introducing pinning to posts and replies in channels. We will share an update as soon as one is available.
The ability to use multiple Teams accounts at the same time is supported on iOS & Android today. The feature team is continuing to work on support for multiple accounts on desktop. We’ll keep you posted as we have more details.
