Well, I shared your opinion for a long time. But Johan put so many improvements into chordpro (including grids and ABC support) that it's definitely for all now and not only  "songwriter" or "song singer" any more.

I've used and still use iRealPro occasionaly since I collected a lot of chords in it when I didn't consider chordpro usable.

But you definitely should look into ABC, which MS already supports (though I consider it in beta pase).

It's wild what you can display and edit with it "live" including grids but also melodies, chords, lyrics, complete piano and band scores. (What it isn't is a rhythm accompaniment like iRealPro, but I don't think that is what you are after).

Unfortunatly is is absolutly not a pro tool for jazz or advanced bands...
I-Real is an "amateur" developpment, but structure and chords are more ralistics to create an arrangement.

And Chord Pro do not solve the main problem : you needs 2 to 4 sheets for a band : UT, Bb, Drum, Lyrics, etc...
