You may notice at the top of an average finder window the toolbar containing small icons to help you work better with your make. You can of course right click and customize your toolbar from the appropriate menu. But I have found a cool tip by accident that lets you change the view of the toolbar. A bit mundane but cool none the less.
In the top right hand corner there is a small button that hides the toolbar and the sidebar, showing a more cut down view. If you command click it the toolbar will change. You can do this a couple of times as it navigates through the different sized text and combinations of text and icons.
It is a very simple tip but it is a quick way of changing the layout.
Edit: Stupid mix up of key commands, my bad.
