Embed PDF VIEWER IN TEXMAKER

As a default, in Texmaker the output PDF from your LaTeX code pops up in a separate window. I prefer the PDF to be in the same window as my code so I don't have to switch between windows as much, however. So how do you get the PDF to show-up in the same window as your .tex code...

• ​Click Texmaker > Preferences
• Under "Commands" tab, under "PDF Viewer," check “Embed.” 
• If you have a small screen, like I do, you can’t really see this option (see screenshot below!), and there is no way to expand the window. (Hello Texmaker! I love your software, but this is an issue). 

​Hope that helps somebody! 

I'm using OSX 10.9.5.
