Yes I see your point Daniel, but Estigy captured the idea—one click instead of two. To me, the ideal would be for a click on one of the four "design" buttons to 1) activate that property (toggle switch on the left side) and at the same time, 2) enable the "design" button which was clicked (right side).
In other words, it's just a programming change, not a software design change... the current behavior makes sense!
Or, even better: have a keyboard shortcut that activates the "slur design" property and toggles between the four designs... (I personally dislike having to move my hand away from the keyboard to grab the mouse! I know,
— but when I'm fighting a strict deadline every second counts, and I'm flying through the music as I copy it from manuscript, no joke!)
I get it, you're changing the checkbox state through the default setting in the engraving options. Makes sense! Perhaps we can implement e.g. "(mp)" in the popover to automatically add the parentheses? And implement ">n" to automatically enable the niente
option on the dynamic being created?
Again, icing on the cake I suppose...
Thanks Daniel, Estigy, and K_B for your insights!
