For Headway, it's ok but missing some important aspects

Quick access to all hooks present in Headway

and

Infinite customization in infinite combinations.

This is not quite correct. You cannot target individual blocks by ID, so the hooks are useful for global customizations but this is rather limiting.

Fortunately you can use your own PHP, but then you can also just as well use a Headway Custom Code block, or a child theme without the need for another plugin..

Unfortunately my requests for more information have not been answered, and now I am worried that the plugin is not being kept updated.

It works in 3.6, but for how long?

That is not to say I don’t appreciate what it does, it is very handy and I like it a lot, but is missing some important functionality.
