In the script editor, I would like to have the ability split the window so that I can see 3 or more sections of my code at once.  That is, when right-clicking on the line numbers on the left of the script editor and selecting "Split", I would like the option to specify how many splits I would like to have.
 
Often I find myself needing to compare 3 or more sections of code to each other.  Adding this feature would make this task much simpler.  I would hope implementing this would be relatively easy.
