Adii Pienaar has teased a new WooThemes features, Sidebar Manager (working title) over on their blog. From the screenshot above, which is currently all that has been shown, it seems to be a screen for creating and managing widget areas, similar to the way menus are now managed.
One of the big feature additions to WordPress 3.0 was the menu editor, which was contributed in large part by the WooThemes team. Could the same thing happen with this new functionality? Adii, in the comments of that post:
If this functionality is well received, we’ll definitely try to get this included in a future WP version.
