@Soundavid Hi,
I'm using the table mode in a similar way, and I was wondering if it's possible to change the button's text with a callback (not in the onInit).
For example, in your table, could you change the text of some buttons in your 'MIDI Learn' column to say 'Unlearn' if certain conditions are met? Or, once I set the text in the onInit, am I pretty much committed to it?
