1 - opening the Field Description the popup open the text editor, where, entering "FIRST NAME" for example, what is saved is the JText string "COM_CCK_FIRST_NAME" we can manage with Language Overrides.
Is it right to have the text editor into the Field Descritpion popup ?
2 - Using Joomla Overrides (in not a problem only for FIeld Description language string), the rules /n /n/n to go head in the sentence seem to don't work.
Please, Do you have any trick to go head in the sentence into the Field Description tooltip ?
Do you think could be a joomla bug ? (/n /n/n when entered in the Backend are not visibles in the Frontend also just as text)
3 - When entered for the Button - Submit Field "Save & Close" the "?" tooltip isn't shown in the Frontend. Can you confirm ? How to have it ?
