I think we can generalize this by letting the user set a preferred edition 
mode for a track. But for the sake of consistency, it should still be 
possible to edit a track in any given mode.

Another problem is that there is no single way to write a tablature out of a 
given music piece, since there can be different fingerings for just about 
anything, and some things can't be fingered at all.

So generating a "playable" tablature out of a music piece is far from trivial 
(I wouldn't tackle this in a serious way until post 1.0), which means we have 
to keep the user's indication around (this note is played at this fret, 
etc...).

Sounds more like a job for a MetaView class.

The staff bit (lines for each string with fret numbers on them).
