Describe the Scenario

Trying to make an additional settings page for my bookstack theme. I can add a new category to settings.layout and have a custom settings page, but to be able to access it I need to add an entry to the settingCategories in app/Settings/SettingController.php, which does not seem possible through current theming options.

Exact BookStack Version

v24.03-dev

Hi @LachTrip,
Yeah, the categories are not made customizable in any way.

I guess we could change this up so, instead of validating the categories by fixed array, we could validate them by checking for an existing matching view file. Would probably be best to move the existing setting category layouts into their own view folder though to prevent any pollution in that respect.

Now achieved via your PR #5255, thanks again @LachTrip!
