Hi,

> I would also like to have more functionality for additional buttons

ImageJ2-style Command plugins support any number of extra buttons with
syntax:

  import org.scijava.widget.Button;
  ...
  @Plugin(type = Command.class)
  public class MyCommandWithHelp {
  ...
  @Parameter(label = "Help", callback = "help")
  private Button helpButton;
  ...
  private void help() {
    System.out.println("Help button pressed.");
  }
  ...
  public void run() {
    System.out.println("Command executing");
    ...
  }
  ...

See here for a demo of SciJava parameters in action (though not a lot of
extra buttons):

Curtis
