Sorry I'm note yet familiar with xF terminology, but is it possible to modify a template (without hook) BEFORE it is rendered. If I understood correctly:
- "Template_post_render" is similar to vB "parse_templates" hook
- "Template_create" is a way to cache template. I first thought it was similar to vB "cache_templates" hook, but it seems there's no way to access $content variable from here.
- "Template_hook" is used to modify the template before it is rendered but only between hooks.
