Glad you're enjoying Ardour and thanks for supporting our work. Things aren't often "ported over from Mixbus", though there are a few features that do start life there (the new perceptual analyzer is one good example). The pianoroll stuff was started so that we could do clip editing. It appeared in Mixbus first because ... well, let's just say that there was some disagreement about when it was appropriate for that stuff to go public, and the release of Ardour 9.0 represents the ardour team's judgement on that :)
