I use Okular to open, say 5, PDF files. Now I need to find one PDF file, say "HelloWorld.pdf"
However, when I click the Okular icon, 5 small windows show up on the desktop. The windows are so small that I can not tell which one is "HelloWorld.pdf"
I hope Okular has a "Window" button, so that when I click it, it will show 5 PDF file names, and I can easily choose one. Or maybe I miss how to do it, since I think Okular should have a similar function as it is a famous PDF browser for Ubuntu.
