@ManUtopiK -

Tailor comprises two parts: the "sidebar" and "canvas" (or preview window), presented in an iframe. The is_tailoring() method is simply used to determine whether one is in the "sidebar" portion of the app (as there are styles and scripts unique to the sidebar).

I'm happy to add a check like the one that you proposed, but would like to understand more about the potential use cases for such a check. Do you have an example of when/how you'd use it?

Cheers,
Andrew.

I use it to display information on front-end for logged-in user that got permissions to edit posts. Also, the edit post link in front-end is replaced by a tailor link when the post has been tailored, useful to prevent client mistake about #41.
And I use it to add a class in the article body...
But I think other use-cases can be found!

Agreed, I like that idea.

The simple function below returns true if a given post has a Tailor layout.

public function is_tailored( $post_id = null ) { $post = get_post( $post_id ); return $post && false != get_post_meta( $post->ID, '_tailor_layout', true ); }

I have this as a method in the Tailor class, so to access it will be identical to your original example:

tailor()->is_tailored()

How does that look?

That's look perfect! You're awesome :)
