not seeing my folders when doing Save or Attach
With my update to Sierra, I've noticed a change in the window that opens when I'm looking for a file to attach to a Mail message or when doing a Save As. In the sidebar, the only visible file location options are Devices. Previously, that window looked more like the Finder window with more options for locations. To find a file or to get to a folder that's several levels deep inside other folders, you have to click on each one and work your way down. My root user folder isn't even visible, so I have to start at the top level of the HD each time. This is very cumbersome and I hope there's a way to make this simpler. Thanks.
