Just a minor little thing.
For Windows you can double-click on the "Notes" tab or "Link" tabs and it will either expand to full screen or return to normal size.
For the Mac clicking on the "Notes" tab does nothing, clicking on a 'Link" tab will open the link.
If you click just above the "Tab" (Content tab Top) it will expand or contract it's size. (Same as Windows)
When the Content Tab is set to left, you need to click after the last tab to expand or contract.
