I tweaked how "holds" are generated (this is when a connected line of notes come at you). Now, you can have multiple small holds closer together, or a small hold not cancelling out a close "big" hold. It will also try and do a better job of making "holds" at the start of a singing section, instead of the middle.
I also made the song choice "stick" if you leave before the end of the song finishes (say, if you want to change difficulty and jump right back in).
Enjoy!
