At the moment you can display only library name as a title of a tab in vertical tabs widget if using multiple libraries.
The widget should be modified so:
It is possible for a developer to select which field to display as a title for each tab. This should be possible both when vtabs are using just one library or combining more.
It still should be possible to choose a library name as a title, instead of a field
Example what should be possible:
For a "Question set":
For "Multichoice" library I want to display "Question" field as a title
For "Drag and drop" library I want to display "The title of this question" field as a title
For "True/False" library I want to display library name instead of a field name
For "Fill in the blanks" library I want to display "Task description" field as a title
Developer can choose which field to show as a tab title in vtabs
