Musescore sorely needs a metronome.
Many people use Musescore to make MIDI files that they can practice along with.
Right now, I'm using MuseScore to transcribe drills in my sightsinging books.
Would be great to have a metronome so that I can practice the exercises while keeping in time.
Manually adding additional staffs with clicks,claps,etc shouldn't be necessary.
Also, there should be an option for a pre-click count (for ex. 4 clicks) before starting playback.
