Dashboard is a labelled link at the left of the page bar on every page, so returning to it no longer means opening the navigation menu first. In the sidebar and the navigation panel, Dashboard is a link one size larger than a tool row instead of sharing the heading treatment used by All tools.
The Personal or team selector shows the current selection beside its initial, and lists Personal first with your shared teams grouped under Teams. The navigation panel and the phone menu also label it Personal or team.
The navigation panel no longer carries a Navigation heading. Its two controls are named for what they do: Keep sidebar open puts the sidebar back beside the page, and Collapse sidebar gives the page the full width.
