No, I see it differently.
The chords should be in the chordpro-file as they should sound and in the display as they are played.
If a file says: [E] [B] [F#]

- a keyboard player can import the file as it is.
The following appears on his tablet: E B F#

- a guitar player can add {capo: 2} before importing or set "Text Display Settings / Capo: 2".
The following should appear on his tablet: D A E (and "Capo: 2")

This means that both can play together and use the same file.

I had assumed that {capo: 2} in the chordpro file triggers exactly the same thing as setting it manually in "Text Display Settings".
But the difference is that the "Eye" has to be switched on manually.
