The address bar
Type an address and it goes there. Anything that does not look like an address goes to a Google search, and a bare domain such asexample.com gets https added. The three buttons on the left are Back, Forward, and Reload. While a page is loading, Reload becomes Stop loading.
Click the three dots at the right end for Hard Reload, Copy Current URL, and Zoom. Zoom runs from 30% to 300% in steps of 10%. Links built to open in a new window also continue in the same panel instead of raising a popup window.
App shortcuts stay live inside the panel. Cmd/Ctrl+T opens one more browser tab, Cmd/Ctrl+W closes the current tab, and Cmd/Ctrl+\ splits the view.
