Excellent! Thanks Wayne. Thanks also for an amazing tool!

For anyone else out there, here is a code snippet that may be useful (or
may not). It appears that the buttons for ThresholdAdjuster are inside a
panel:

ThresholdAdjuster ta =
(ThresholdAdjuster)IJ.runPlugIn(ThresholdAdjuster.class.getName(), null);
//Now I have a reference to ThresholdAdjuster
Component[] comps = ta.getComponents();
IJ.write("There are " + comps.length + " components in ThresholdAdjuster.");
for (Component c : comps) {
    IJ.write("Component " + c.getName());
    if (c instanceof Button) {
        Button b = (Button) c;
        b.setVisible(false);
        IJ.write("Found Button " + b.getLabel() + " and
setVisible(false).");
    }
    else if (c instanceof JButton) {
        JButton b = (JButton) c;
        b.setVisible(false);
        IJ.write("Found Button " + b.getText() + " and setVisible(false).");
    }


Output:
There are 7 components in ThresholdAdjuster.
Component canvas0
Component scrollbar0
Component label0
Component scrollbar1
Component label1
Component choice0
Component panel0
