Again. - This statement is incorrect - it is faster in Dorico than on paper. Not to mention that it would likely look terrible on paper - while Dorico automatically re-adjusts the note spacing.
Again - this is not a bad idea - it has some merit. But AFAICT you seem to be the only person on the forum who thinks this is significant deficit in Dorico. There are scores (no pun intended) of missing features that are far more critical for many users. I suggest (if you haven’t already done so) that you take a look at the Dorico 5 Most Wanted thread to see what other users feel are important.
Couldn’t agree more.
