The existing “Split-View” functionality in Konsole certainly has its rationale (http://dot.kde.org/2007/05/23/road-kde-4-konsole-gets-overhaul), but it is not the one I expect to use.
I am trying to implement a different split, which works similarly to the one found inĀ Terminator.
A picture can explain it better than words:

The work-in-progress is at this “personal” konsole repository on gitHub, which I will keep aligned with the master, hoping that, once finished, it will be possible to integrate this implementation into the KDE repos.
