When using "Draw a Path" tool, the default dragging of tangents has "Angle snap" activated, with shift-drag to make it free. This is not convenient when drawing something that doesn't need any snap to have to use shift all the time. This should be switchable behavior: please add a "activate angle snap" switch in the tool options panel-> "angle constraint" section, with default set to off.
This bug is in Karbon at first. Should I file a new one, or is it possible to redirect this bug to Karbon list?
