Good News! Some days ago Microsoft published a release candidate of their first update to TFS 2017 (Release Notes).
The very big improvement is the new personal homepage.
If you’re using Visual Studio Online (VSO) in the cloud, you can activate the new homepage by clicking on the preview link.
Have a look at the Work tab. TFS has now an overall report of the open work in all team projects. This is the great new feature we have waited for years. Thank you Microsoft!
Nw you can always keep track of your open work in all projects.
