I think it would be nice if SliderCtrl option "Jump" will be supported by LayoutDesigner.

First of all, We need to improve "Jump" method by replacing return value from "void" to "SliderCtrl&". (SliderCtrl.h - line 45):

SliderCtrl&   Jump(bool v = true)              { jump = v; return *this; }

The second part is to patch .usc file just adding one line of code. (CtrlLib.usc - line 1261)

bool Jump = false;
