Add TO-Do app as a tab in Teams
Rather than having to run the To-Do app separately make it a tab in Teams as most to-do items relate to work in Teams
This is in the works, please see our announcement post from Ignite!
I read in the comments from the link provided above per Polly Davidson this functionality was going to be available mid-year this year....It's now September. Update please??!!
These requests should be combined... https://microsoftteams.uservoice.com/forums/555103-public/suggestions/37870747-integrate-microsoft-to-do-with-teams
