Maybe a “revert to default” configuration is a “no good button” to place into IDS/IPS config.
But write into docs which are the “default rules and behavior” for NethServer may be a good idea.
You do not know how many such button is useful for the support team!
Default categories are not documented because they hard coded and could be changed during time.
So, I’m not sure they should go inside the manual.
But if you want to propose a PR, this is the list: https://github.com/NethServer/nethserver-suricata/blob/master/api/configuration/read#L62
