Yes, that would be super helpful! For example today I drew a meander structure (fancy, with splines etc.), so I got quickly > 800 constraints and now adding further line/arcs, takes longer and longer.
However, what about having an option to turn off the solver completely via an option? Then, with the blocked solver one could add all the arcs one needs, and constrain them and when the sketch is basically ready one could unblock and let the solver work.
