This is so amazing that they are working on it! I checked the current pre-release build and couldn't believe it when I tested it! Still it seems to be choppy when the scrolling movement approaches the end. I posted about my experience also in the current pre-release thread (
https://forum.cockos.com/showthread.php?t=233293) with a video link showing my experience.
Do you guys experience it like this as well?
Let's hope they will go into detail with developing this feature!
