Hold down the Ctrl / ⌘ key to change the location of buttons in the browser’s user interface.
Just press down on the Ctrl / ⌘ key on your keyboard and with your mouse drag and drop the button where you’d like to see it instead. A line showing the new location will appear when the button can be dropped.
There currently are some limitations to where buttons can be moved. For example, you can’t move buttons from/to the right side of the Address Field. But we’re not done with the feature just yet, so you can expect to have even more flexibility in the future. 😉
