Auto scroll down function to play with Hookpad

Thanks to Hookpad for helping me to compose my first song: it is really amazing!!!
When I try to play-back my song in Hookpad with my guitar, the screen does not scroll down simultaneously with the cursor position…so I have to stop fingering to pull down the screen to read the notations and chords.
Mix is very powerful, yet it is good to allow users to specify any section to mix with special features e.g. I want to include choir in the chorus section only,but if I chose Choir in Harmony, Choir appears from the beginning of the song till the end. This is not the effect I want. Hope this can be improved.
