The purpose of the simple program was to “Hide” and then “reveal” the horizontal arrangement. I never got that far, but found another issue first.
In Button 1, if I enable either “arrangement” block, the program becomes unresponsive. It continues to be unresponsive after the block is disabled again. I have to quit, deinstall and reinstall the companion in order to get the program to be responsive again. The same thing happens if I tap Button 3, which also sets the arrangement size.
