Please add the ability to lock the following global tracks on a track level as well as on an individual event/item level :
1. Marker Track
2. Chord Track
3. Lyrics Track
4. Tempo Track
5. Signature Track
6. Arrangement Track
Turns out the only global track that can be locked (track + individual events) is the video track.
I often find myself accidentally moving markers, arrangement sections, tempo points etc. and messing up everything. An ability to lock them would allow me to not move them accidently and mess up my sessions.
