Hm I had started on this at one time but I guess I never finished it. I'll put it back on my list.
Subject: kdeextragear-2/kst/kst CVS commit by staikos: after a marathon session of tuning and tweaking the coordinates, I finally have the datamode cursor working. It isn't pretty and it flickers a little bit, but it works.
