I think I am a bit confused here. Are you talking about games other than 
ReadingNoteNames? If so, when you speak of chords are you talking about more 
then one note at once or are you talking about chord symbols and figured bass? 
There can be a game made that user is expected to analyze the chord or 
something like that. In reverse a user may be required to fill in chord tone 
that match a chord symbol.

This makes me wonder how we are going to deal with versioning. If I write 
something that uses the above, people who are using 0.8.6 will have 
non-functioning scripts if they "Update commands from the internet"

This sounds clear as to what it is.

Ok. So you recommend checkmarks and graphics to be standalone but when notes 
are inserted you recomend placing a note directive on them so that the cursor 
does not thrown off and make everythig off track.

I read through the Conductor example and have implemented displaying the score 
in big numbers into the games. I am not using directives to keep track of 
"units" and "tens" though. I am not sure if I understand your usage of them. 
What I ended up doing was to create a procedure that converts the score number 
into a string and then performs an operation to each character of the string. 
The string is then converted to an integer and then the corresponding graphic 
is placed on the screen.

Thanks, I will keep my eye on them.
