User definable styles are a great idea.
I would use the same appearance for all songs (or maybe a small number of different styles), but would like to adapt lyrics size and chord size per song to make best use of available screen space.

Style settings for parts of a line are one of the things that I miss most in ChordPro.
For me there are mainly two use cases:
1.) We have a lot of songs with a main singer and fill-ins by a background choir.
In this case I have the need to mark the lyrics parts where I have to join in for singing background. (Mark words with highlight, bold, underscore or whatever)
2.) Sometimes it's hard to remember which syllable is the stressed one. Marking on character level with underscore would be my preferred way to do that.

The second feature that I bitterly miss are chord grids.
They are already part of ChordPro V5 but not yet supported by MSP
