We play a good number of arrangements that incorporate key changes, some of which require re-capoing the guitars mid-song. It would be really nice to be able to use a smart button to apply a new capo position "on the fly." IOW the button would change the "Capo" setting without having to open the "Text Display Settings" and change it there.

I'm trying to visualise how this should work.

Assume you're playing a song in the key of D, with chords e.g. D A G, capo on 2. Then on the 3rd repetition you want to shift key to E, with chords D A G, capo on 4?

If you recapo, you play the same chords even though they sound higher.

Otherwise, if you are one of the musicians that play without capo (keyboard, bass, ...) you would like the chords to be transposed.

@jlgtx: You really want to realize this with a smart button that you press during a performance and in the meantime change your capo? For me that scenario needs to be prepared in advance, with different sheets for the guys that change the capo and for guys that play without.
Something pretty special for certain songs and arrangements. You should be able to solve it using the features that are already available instead of asking Mike to implement a new exotic feature.

Many of our hymnal arrangements have half-step key changes. We usually have multiple guitars, and they often select different capo settings. Some of our guitarists also like to re-voice mid-song at times, e.g. for a final chorus or something. Changing the capo setting using the dialog is nowhere near as fast as a smart button, and painful experience has taught me that having multiple “custom” versions of arrangements leads to confusion. 

How this would work: I have an arrangement that is in B major with a key change to C major for the last verse & chorus. The bass player just uses the ChordPro as-is. One guitarist wants to play in G (capo 4-5), another wants to play in A and change to C (capo 2-0). Each player can use the smart button for a quick one-tap custom capo change, giving them more time to move their capo and keep playing.

This is no more “exotic” than any of the other smart button actions; in fact, it’s exactly the kind of thing smart buttons are for.

@ jlgtx,
since a lot of years, I´m doing arrangements for a group of 5-6 guitar players, 1 bass, 1-2 percussion players.
And, yes, sometimes we have to change key, but never capo (as an example: Three Wheels On My Wagon....key change every verse).
I heard "change capo within a song" the very first time......even it´s technically possible, of course.

IMHO, it´s not a question of mobilesheets, it´s more a question of skills of guitar players.
Just as a hint: Play power chords in such a situation, or for Latin/Jazz shell chords, so you never need any capo (change).
But this leads to far "out of topic" related to mobilesheets.

e.k.
