Re the site, it would be quite good to have a roadmap of features you plan to implement, and some rough Idea of the timescale. I know on youtube we discussed things like having song sections that could repeat, then only move on with a command, etc. If there was a central repository of upcoming features that could be referred to it would be good and might save some repeated requests.
Also a list of bugs, and when they have been fixed would be good too. I noticed a bug today, but it was reported 9 days ago, and there have been updates since then. I'm not sure if it has been addressed, as it is intermittent. It is there on a song I created, but when I open a new song, it is absent from that. So I'm not sure if it is fixed, or has been partially fixed. I'll put a specific post about that in the relevant thread in bug reports.
