I was just reviewing your config again.

A challenge will be...... returning to a display and source, after tuning a seperate display with a different source, and not sending the macro commands again.

1) Hopefully your source selection is a 1 or 2 step macro that doesnt effect what is being displayed if it is already on the correct inputs.

2)If not.... consider two buttons for each source per display. One that contains a macro and one that does not.

3)Or add 4 buttons at the bottom of every page that directs you to the control of the desired source as selected.
