Advanced Selection Filter (cetain notes)
After I've figured out that I can adjust the pitches of several selected notes at the same time I came to the thought that a selection feature that would allow me to select e.g. all Bs (or even better all Bs inside a marked area) could solve all my microtonal and custom key signature problems. So if we go to Select -> More it would be great to have another line where we could enter notes like B, Bb (of course accidentals should have an effect, so I can tune all Bs in a marked area to the intended pitch, with less clicks and afterwards adjust all Bs that I want in another pitch manually. This would save a lot of work.
