The feature team is still considering this item. No confirmation yet.
Yes, my teams have been using Slack and Basecamp for years. It is important to be able to import from these.
This feature request is working its way through the backlog queue. No new details are available yet.
Agree. My organization also has an established SharePoint site with several document libraries. In a channel when adding a tab, I was successful in linking it to one of my established SharePoint libraries and that seems like it will work great. But what I would like to do is be able to Remove (or at least Hide) the default Files tab in the Teams Channel so that the team only sees and uses the specific SharePoint library I have linked for them.
Also, it doesn't seem possible to move the first two tabs (Conversations and Files) to a different position. So unfortunately they will always see the default Files area ahead of my linked SharePoint library that I want them to use.
This feature item is still in the works. We will keep you posted as we have new info from the feature team.
The team continues to make progress on this. We will share more details as we have them.
