Many designers and administrators never specified a text for the section title that is displayed above a UI extension when it is presented to a user. They probably did not realize they could use the Title field to do this. This is unfortunate, because without a value in the Title field, the text that is presented as the section title above the custom fields defaults to ‘UI Extension’. That may sound rather technical and therefore confusing, especially for end users when they see this in a request.
To make the purpose of the Title field a little more intuitive, its placeholder text has been updated from ‘UI Extension’ to ‘Section title’.
What has also changed is that the Title field is now required for every UI extension. Together these two adjustments should help avoid users seeing the default section title ‘UI Extension’.
