The Thesis Theme was one of the first premium theme frameworks that I used and it’s been my first choice for many years. They recently just bought out version 2.0 and have completely rebuilt everything from the ground up making this a very interesting option.
Introduction to the Thesis ‘Skins’ System
Skins work in a similar way to frameworks and child themes however in this case you have a central theme that controls much of the code base so that you are always using the latest and safest functionality whilst controlling the look and feel through a skin.
Thesis manages this by allowing you to change many of the design options with a custom settings panel and overhauls the rest by installing skins containing code that sit inside the theme and add extra layers of design and functionality.
The new dashboard editor allows for limited drag & drop design functionality, design settings page and also has a built in skin manager so you can export and import ready made designs to your site in seconds.
Thesis has always placed a relentless focus on SEO which means you are best to use the built in SEO features rather than a plugin if you choose this theme.
Unfortunately I would say this theme is more relevant for the more intermediate/advanced WordPress user so make sure to check out several reviews or tutorials if you want to fully customise Thesis yourself.
Where to Get Pre-Made Thesis Skins
Themedy has one of the widest range of Thesis skins available under a single subscription offer and packs in a lot of value if you plan on designing multiple sites with the Thesis theme or Genesis Framework.
