 I really don't get this. If I'm drawing a line that connects two already horizontally aligned dots, why does FreeCAD add a horizontal constraint *anyway*? It creates a redundant constraint that messes up everything and it seems so easy to avoid. These issues are everywhere and make the sketcher miserable to use.

 I don't know what their problem is, but both Trackball and Turntables (they have two "turntable" options) orbit systems are very uncomfortable to use. Turntable completely blocks one axis of rotation and seems to always orbit from the wrong place (it places the origin in some imaginary spot at the center of the screen rather than say, the object) and trackball is just insanely finnicky.
