My religious suggestions:
- Add religion effect "pentarchy = yes/no", associated with "autocephaly = yes/no". If explicitly set one of these parameters - (de)activated pentarchy and autocephaly, but only autocephaly activated, if set "pentarchy = no autocephaly = yes" and vice versa only pentarchy, if set "pentarchy = yes autocephaly = no". Required for religions subordinate nobility, such as the Insular Christianity.
- Allow specify provinces are pentarchy like holy sites (pentarchy = <religion/religion_group>) to replace hardcoded pentarchy provinces.
- Add religion effect "title_autocephaly = <localisation_key>", to specify title of by the head of the Autocephalous Church
- Add religion effect "cult = <other religion same group>". Required for in religious cults, such as catholical and buddhistic monastic orders
- Cults cannot attacked or conversion the parent religion and vice versa
- Cult inherit all not replaced parameters from parent religion, including religion head
- Religious liege of cult head - head of parent religion, that is heads of catholical cults can pay tax to the Pope
- Parent religion and all cults always can intermarry and inherit theocratic titles (except religion heads) from each other
- Add religion effect "can_lead_parent_religion = yes/no" (default: no) allowing cult member inherit parent religion head and elector titles
pentarchy = somerigion can already be set on landed titles IIRC
