Expanding functionality of the selection filter

The selection filter is probably one of Musescore's best ideas, and I think its functionality could be expanded upon. Here's a few ideas I had.

• Select specific notes (comma separated):
  A text box where, when not empty, your selection is limited to the notes typed in (A-G). If there is a second character before the comma and if it is a b or a # it would interpret that as flat or sharp, a number would specify the octave, a dash would specify a range (ex. A4-G5)

• Select lowest/highest notes in chord
  useful for chord editing and quickly creating inversions. Single (non-chord) notes would be ignored by the selection

• Select all notes with/without accidentals
  useful to more quickly correct mistakes in multiple chords within the same measure

• Select every n-th note
  might be cool for quickly playing around with/editing rhythms of multiple measures maybe? I'm sure there must be some use case for something like this

• Bonus idea:
  when selecting multiple notes, have pressing shift+(A-G) stack that note on top of every note like how you would make a chord regularly and automatically select all of the instances of that note in case you want to shift them all to a lower octave
