The article discusses how to change the title of the Business Process Error popup in the UI of a plugin. While there is no supported way to do this, the author suggests using a MutationObserver to modify the title. They provide sample code that can be added to the form onload or as a library for a custom ribbon button. The code allows you to change the title to your own custom text. However, it is important to note that this customization may stop working in the future and may require modifications to the code. The author also mentions the possibility of further customization by parsing the plugin message and calling a JavaScript function to update something on the form, but warns against relying too heavily on unsupported customizations.
