Mandatory fields unfilled in other tabs are not easily findable

[Mte90]

Do you have any examples?

• In a model use fieldset to organize the various fields
• Put fields that are mandatory in other tabs (fieldset)
• Save the model and you will get a warning, that warning is just on the tab where it is the user but there is no way to understand that there are other fields to fill in other tabs

Describe your feature request

In my opinion the tabs with mandatory fields in the title should have the red asterisk as base so is not needed anything else to alert the user.
