2.0

This adds a number of features, but is definitely a breaking change.

Added

• Capability to define multiple directories.
• Support for child themes (loads templates from child and parent, but child templates override parent ones). This feature inspired by alfacommunication-alessandro/plumbing-templates fork.
• Built-in support for roots/acorn.
• Better internal documentation.

Changed

• Internal behavior and functions. register_template_directory() should work as before, but all other functions are likely gone, different, or produce different output.
• Relies more heavily on Finder to locate, filter templates.
• Update names for filter hooks to be more reasonable and extensible.

Initial release

This implements the most basic version of this feature: To allow a user to quickly and easily set up a specific directory for page (or other post type) templates.
