When creating a taxonomy there is a tick box for applying it to a post type. However, the application is not made. The user must go back into the post type screen and chose the new taxonomy. not a big deal, but just wondering if it's something that should happen automagically when creating a tax.
It's supposed to be working, I'm sending everything to the function correctly, I'm thinking it's something a bit deeper regarding timing of running the register post type / taxonomy functions in a specific order.
I've set it up to add it during the post type/taxonomy registration, but I do need to add some hook to save it to the related object. Though I'm not sure entirely what WP wants, the functionality in each 'register' itself doesn't actually enable it on both sides, only one. So I'm not entirely sure what they intended with this or maybe it's a bug of their own.
After reading a bit, they should be synced, so I'll make sure to update the code to save it like a bi-directional field would save (update it from either side and it'll update both values).
Here's a task for you @mikedamage
Looks good, close if it works for you in your tests. Thanks!
