Can't read titles in minimized windows

Try Ctrl+Tab

The full name of the file, if longer than what will fit on the tiled preview, will be shown in the bar just under the "Open Documents"...for whichever open document is being highlighted.  Repeatedly tapping on Tab while continuing to hold down the Ctrl key will cycle through the open documents.  When you are highlighting the document you want maximized, release the keys.  This works whether the files are minimized, maximized, or whatever.  You can also just click on the one you want with the mouse.

Select "Window" at the top of the screen

Select Window>Tile Horizontally

Then

Select the Maximize button on the widow you want.
