Color selection of playback cursor.
I wonder if it would be possible to change the color of the playback cursor that moves as the score plays. I like the blue as it is, but I could see in the future a preferences setting that let there be a custom colorization. This could be beneficial depending on what kind of display settings are being used or just out of favoritism for a particular color, especially in conjunction with custom page colors or wallpapers.
With this in mind, it also follows that the four-voice color highlightings could allow for customization. I know this isn't a priority for functionality's sake, but the reason why I bring this up is for possibly recording video-captures of playback. In doing this, it would be nice to have control over these colors for presentation purposes.
