bFooz, awesome that you're spending all this time to thoroughly test Reaper's notation features. But I'm not exactly sure how deep you should go, when you're starting to compare the look of things in Reaper with the look of things in 560€ worth of professional engraving software (yes, it's overpriced, we all know).
I mean, sure, we want the best for Reaper, but I feel all these notation things could possibly be better done at a later point when Reaper gets articulation management (that's still on the table, right, schwa?)?
