You have heard many times that Lancelot was a superkaramba applet in the beginning, and that later I screwed it up by turning it into a menu. :)
In this video, which is demonstrating the developments of the /Plasma Applet Browser/ in the era of pre KDE 4.0, sometime in the middle of it, you can see the first version of Lancelot for Plasma which was generally the crude port of the SK one.
Absolutely no connection to the present one :)
KDE looked so terrible back then - the amount of change is really amazing :)
