Questions about the Profile FAQ module (and a comment regarding 'forms')
Using Jamroom
I've got this module updated in the Marketplace that has the help setup for the category field and it is now set to required, it is needed to keep your FAQ's organized. Update via your ACP > Core > Marketplace > System Updates and let me know if you see any issues.
You can modify the language strings through the ACP > Profiles > Profile FAQ > Language tab.
As far as the updates you've suggested, I'll see if they can be done, but there are no plans at this time to update this module. It would be low on our priority list at the moment.
