Font options and more colors are two separate things. This idea is mainly for added font options.
SO, if having more colors is more important to you, please add a vote to this separate idea:
Noteflight has a Standard Font and a Jazz Font, but how cool would it be if you could design your own? Maybe Noteflight could add a section where you draw each note and you can create a font pack and download the fonts of others. Not the most essential thing, I just thought it would be cool.

How much longer till this comes out? It's been almost 3 years.
Musical pieces like Mars by Gustav Holst use con legno on string instruments. Con legno is hitting the wood of the bow against the string. I think it would be cool to be able to listen to this in playback.
