Why can't notation be shown "on the fly"?

I mean, any notation editor knows the pitches/timing/etc encoded in the score, and it should be able to trivially show it to the musician in a customized way - transposed to the instrument, if neccessary; with or without fingering information where applicable; and in custom/wierd notations like this one.

Of course, printed/photocopied scores can't do that, but we're not in stone&paper age anymore and can fix things to improve functionality.
