New dialog functions would be great for the future. Modeless dialogs are very handy.
Perhaps an alternative could be to have the option to add additional buttons to the waitForUser function?

As soon as gd.wasCanceled() is called, the script or macro aborts if <esc> or <cancel> was pressed.
> script += "IJ.showMessage('Hello');\n"; > script += "wasCanceled = gd.wasCanceled();\n"; > script += "IJ.showMessage('Hello again');\n";
and you press <cancel>, the 'Hello' message will be there, but you won't see the 'Hello again'.
For JavaScript that you start from a text editor window, that name is 'JavaScript'.
I agree that in principle, checking for 'cancel' or an empty String in your macro should should be more tolerant to future changes than just checking for an empty string.
Nevertheless, a cleaner solution (though some work for implementing it) would be adding "Dialog.enableYesNoCancel(yesLabel, noLabel)" and "Dialog.wasOKed()" macro functions, or adding an optional 'options'

I don't understand why that should make a difference. It also works if I copy the assembled string as printed in the log window and run it from a text window as javascript.
