[PLUG] What do you call it? LibreOffice preview screen?

[Dick Steffens]

I have an annoyance with Libre Office. I have a spreadsheet that I set 
to take up a certain amount of screen space. If I have nothing else open 
in LibreOffice, and I close that spreadsheet, but not LibreOffice, I get 
what I'm sure they intend to be a helpful preview kind of window with a 
column of commands on the left and a collection of recently used 
documents on the right. My annoyance is with how the window size does 
not revert to the size I had set for the spreadsheet when I reopen it.

My problem is that I don't know what to call what I'm seeing so I can 
search and see if there's a way to change it. Any ideas?

Thanks.
