Hi Roy,
No timeframe for the next release yet, and the feature list hasn't been announced yet. I understand that creating 270 buttons and linking them up seems like a lot of work. For a bit of perspective, save your layout and open up the built-in Casio layout. Tap around a bit. That was made by a volunteer user and has hundreds of objects just for decoration, and thousands of little pieces like this.
Sorry for the inconvenience and the mucking, and for taking the hours out of your Sunday for our extended conversations (SOME but not all of which could be repurposed to making layouts). Again, I do NOT recommend using supercontrols send own values and you shouldn't. Take the time to create your layout without using this feature.
Thanks!
