How can I split the screen when the screen splitting widget is not visible? I know the basics of splitting the screen/creating more of them.
While I can split the windows at the right I can't do that on the left, because those typical lines on the left lower corner are missing. Can I make them appear somehow?
Try this:


Open new window by pulling the right top corner
Once you do that you should find the bottom left one in the new window
Pull the left bottom corner to close the old one which didn't have the bottom left pull option
