Multiline text for button labels
It's definitely a pity: it is not possible to have long label text for buttons, radio buttons or check boxes:
// UI_multiline_labels.jsx
// 2021-02-01
var w = new Window("dialog", "Appearance of multiline labels", undefined);
w.t1 = w.add("statictext", undefined, "Some longer text in this label", {multiline: true});
w.t1.preferredSize = [100, 35];
w.rb1 = w.add("radiobutton", undefined, "This does not work at all", {multiline: true});
w.rb1.preferredSize = [100, 35];
w.cb1 = w.add("checkbox", undefined, "Some longer text in this label", {multiline: true});
w.cb1.preferredSize = [100, 40];
w.btn1 = w.add("button", undefined, "Some longer textin this label", {multiline: true});
w.btn1.preferredSize = [100, 40];
w.show();

This is a requirement for dialogues filled not only with short running English text, but with French - not to speak of Finnish ...
The only solution to the problem seems to be a nasty crunch: https://community.adobe.com/t5/animate/need-radio-button-component-labels-multiline/m-p/1064285
This again reminds me of the age of the whole ExtendScript stuff.
