Because this theme has friends. When you get this theme you get them all! But most importantly, all the themes from Aftertype come with a marvelous feature called the Aftertype Assistant.
What is the Aftertype Assistant?
It is a utility that lets you manage and add services directly in your blog. Having an account at Aftertype and using a generated token to verify you have permissions on your blogs, you can do things like adding widgets.
So, as you can see, you will get more than just themes. There is a complete app that lets you manage easily some features that could take you more time by coding or modifying the theme(s).
Aftertype is meant to bring you the tools & you can focus on generating meaningful content
