I have a tablet set up at work that always shows me my VSTS dashboard, which I’ve configured with widgets just for my consumption.
One feature that VSTS is lacking, is a “fullscreen” experience for Team Dashboards - there’s no built-in way of hiding the top menu bar, and the “customise the dashboard button”.
I have created a custom userstyle for VSTS that does the trick. It removes the menubar, shifts the content up 100 pixels and removed the (+) button.
You will need the Stylish extension (or similar) to install it.
I’ve created a Github repo for the custom stylesheet, which you can find here
