As a hub for Teamwork, Microsoft Teams brings together apps alongside chat, calling and meetings. These apps can be proprietary Microsoft apps, third party apps or custom apps which have been uploaded via the app store. In using such apps, members of the team may have specific apps which are their favourite; ones which they either want to access quickly, or ones that they may need to regularly access to several times a day. They may need to have it to hand in order to demo or to evaluate in front of peers. Following on from the recent blog which outlined channel pinning, the team can now also pin apps to the app bar. Channel pinning supplements app setup policies and make the whole app experience fit the user, saving time and increasing productivity
There may be an app your Team frequently uses. For the purpose of this article lets take this app to be Microsoft Flow where the Team is repeatedly adding Flows between apps such as Forms and SharePoint and Twitter and Powerapps across multiple Teams. They could always add Flow as a Tab to a particular Team, but with the increasing amount of Teams this wouldn't make much sense as the Team members would have to remember what Team, or - as is more likely - they are now adding Flow Tabs across multiple Teams which is littering Teams with Tabs which don't necessarily need to be there.
