TYPO3 Core

I had a bug issue for my extension be_secure_pw because of problems to save the ext config.
After 5 minutes of trying I have seen that there are two save buttons in the form and in HTML there are two seperate forms.

I also found out that I have two different subcategories in my ext config.

    # cat=basic/enable/60; type=boolean; label= Special characters: The password must contain at least one special character (!$%&/=?,.).
specialChar = 1

    # cat=basic//60; type=int [2-4]; label= Fitting patterns: How many patterns from above must fit to make the password secure
patterns = 2

• a well-documented wiki page for the ext_conf_template.txt file (I didn't find anything)
• a better separation in the form for a better usability
