Theme Customization in concrete5 5.7
In early May 2014 concrete5 core team posted up a screencast of the new theming options in version 5.7. We like.
Theme customization options have always been a great feature of concrete5, though not one that has ever been the eaziest to use, neither for the theme developer who sets out to the make their theme package customizable by the end user, nor for the designer or end user themselves.
These options have been totally overhauled for 5.7, and they look fabulous - we particularly like the new 'presets' feature.
If you haven't seen it, here's a link to the screencast showing both the customization editor suite and options, as well as the configuration process to make a theme customizable. It's well worth a watch.
