Nested screen sessions rule
While it can quickly get a tad precarious, having a nested screen session is pretty damn cool.

Switching between them is pretty simple. ‘^a’ tells the terminal it’s a screen command. Simply hitting an additional ‘a’ tells it it’s the nested screen, and so on, depending on how many times you hit a (obviously, this would get too difficult to work with, hitting a five times just to send a command to a screen is a waste of everyones time). So, in this image, ‘^a a n’ would shift the nested screen to the next ‘tab’, and so on.

Great. Now do it in split screens, double nested.
