Greetings,
Any update on this? I've recently switched from Illustrator to Designer. I also find the 'Break Curve' functionality tedious. In Illustrator (sorry, only point of reference), one can simply select (or drag over) a segment between two nodes to select the segment. Pressing Delete then removes the segment. In Designer, this is a 4 step process with multiple tools as many have already pointed out. Yowzer!! This operation is so fundamental to drawing with the pen tool I'm finding it difficult to adjust. There must be another solution here that streamlines the process while working within the vector engine Affinity has created. Look forward to any updates.
