There's more...

The TFS marketplace features the free Query based boards extension (https://marketplace.visualstudio.com/items?itemName=realdolmen.querybasedboards), which was created by RealDolmen, and allows you to visualize the result of work item queries on a board. After installing the extension, navigate to the Work hub and select Queries. When opening a query, a new tab called Board will be available to visualize the results on a board:

The extension is available as a dashboard widget, as well as a subpage in the work hub. The Activity Feed gives a summary of all the recent changes that have been made to work items, commits, pull requests, and builds. It tells you who changed a task, who logged a bug, and who committed code. The extension supports configuration, so you can decide to filter out what's not relevant or simply configure which backlogs work updates should be published from. Some people would agree that the more boards, the merrier!
