Currently, (v184.108.40.2061) you can adjust the angle of a slur without changing its shape by ALT-dragging a slur endpoint. I dislike using the mouse to edit slurs, but there is no way (as far as I know) to do this with the keyboard. Could this be added in the future?
It’s something we may add in future, yes.
Good to hear its on your radar. Thanks
It’s a good idea, it will be much more convenient!
