Ease category mapping
The extension comes with a custom domain model for categories (sys_category) and adds the accordant type setting in the TCA control section.
However, this settings enforces to either define other categories not used by the calendar extension to get a strict model class assignment.
From my perspective this is not required and too strict. The categories in the calendar extension are assigned using FlexForm and thus transferred to the view. The only drawback by removing the type configuration would be to have all categories visualized in the category tree inside the plugin configuration in the TYPO3 backend.
I'm looking forward to your response. Find my patch attached. Thx!
