kde4's split screens in konsole

Finally noticed the split screen feature In KDE4's Konsole!

At first, I thought, "This is silly," because the split screens don't work independently of each other like you'd expect -- like split screens in Konqueror, Krusader, and Dolphin.  When you type something in one screen, the same thing gets typed in the other screen.

Here's a left/right view, from PCLinuxOS 2010.07:

I thought this was a bug, but it turns out that it was intentional, as explained here:

It is a console output cloning tool so that you can see two views of the same scroll buffer. For example, if you are a developer, and you need to compile something really big (like say, KDE), then you can read through the scroll at your own pace on one side, while still monitor the output progress simultaneously. This is not a multi-panel model like Konqueror, so much as it is a cloning mode that lets you see more than one thing at a time within the same buffer.

But then I realized that with the use of tabs, combined with the split screens, the split screens can be used to show the output of different commands.  Here's a top/bottom view:

Useful tool for something like viewing a manual page on one side and running a command on the other side!
