Transposed linked staves
MuseScore currently allows you to create a linked staff, which displays the same content as the parent staff in a but select a different style of notation (such as tab format notation). This is useful for creating parts for instruments like the bass guitar, where some musicians prefer to read traditional notation, but other musicians prefer to read tabs.
What's missing is the ability to change the transposition of the linked staff. This would be helpful to create parts for instruments like euphonium, where some players read concert pitch bass clef parts, and others read treble clef parts transposed into Bb. Currently, to make treble clef & bass clef euphonium parts, you have to create separate unlinked staves, and copy/paste the content from one staff to the other whenever you make changes, which introduces a chance for errors (i.e. the engraver forgets to copy the changes after updating the score). Transposed linked staves would remove this extra step and make it easier to create accurate parts.

I was just running into this frustration myself. I teach recorder, and want together a small ensemble. My school has a few alto recorders, but all my students learned soprano. To make their life easier, I normally just transpose the alto part down 5 steps. That way they can read it with their regular fingerings but it will come out sounding in the correct key. I'm doing the same, where I create an unlinked staff and paste the music in right at the end. It's a no brainer!
