Below is a repeat of an issue opened on the developer's Git.
This is a request to allow for targeting of specific blocks using Headway Easy Hooks.
From the Headway Codex:
If you want to use one of the hooks that can take a unique block ID or block type, just replace #BLOCK_ID# or #BLOCK_TYPE# with a valid block ID or block type.
headway_block_close --> this is currently the level available in Openhook
This ability to drill down or target specific blocks does not appear to be available in Openhook, but it would make the plugin infinitely more powerful.
