I have to agree with all this, Daniel. Conductors like to see time signatures after page turns, and splitting a flow just to do that without a vestigial cautionary one hanging on the end of the previous page creates a ton of extra work - changing barlines, messing with tokens and project info so that margin info looks OK, and more layout tweaks. It’s highly inefficient, and on a tight deadline, untenable; I will now have to explain to my conductor why I wasn’t able to add the time signatures he requested.
All that said, Dorico is saving me lots of time in general! But this one thing does need to be fixed. And yes, I know, composers are demanding.
