Say I have 5 different worksheets open in Calc, and I'm trying to switch between them. As far as I can tell, I have two options: use Alt-Tab to switch - by looking at zoomed out versions of the windows, or double click on the Calc icon in the Launcher to show all the windows, zoomed out. 

In either case, it's very difficult for me to know which is the right window just by looking at the general shape of the document, and the title of the individual windows don't appear anywhere.

Am I doing something wrong? Is there a better way to switch between windows? Is there a way to make the titles of the windows appear under them, or inside the Alt-Tab window, like in Windows?
