Settings view close button is unintuitive

Due to the whole quire UI doesn't have anything that requires a X button on the top right, and imagine if we maximize our browser window, the right side is actually pretty empty and usually our eyes wouldn't go to that corner because most things that we usually uses is on the left - our team often came across the issue that we don't know how to close the settings window - very often we actually use the browser's back button, which is not what we wanted to do at all - I'd suggest to have a back button on the top left closer to the project/org name area.
