This is so minor, and with all of the other things needing to be tackled, I am sorry to even bring this up.
But, can the dash between tempo ranges be a little smaller, and add just a touch more space before the start and end of the dash?
Here is one from Finale. While I like so much more the font and look in Dorico, I do prefer a little more space. Maybe not a large as this one, but certainly bigger than what Dorico does now.
