Add the same functionality to AEM Designer for adding a Tool Tip, Custom Text, etc. as there is for editing a default value in a fillable field.
When creating 508 compliant documents/forms where the Tool Tip or Custom Text needs to be entered.
AEM Designer provides a very small window for entering and editing text. Some tool tips have extensive text or have more text than the current box shows
Create the same feature in AEM Designer that is available for a default value in a fillable object (i.e. Text Field). At least the window would be big enough or bigger to allow for easier tool tip or custom text creation and editing.
