UPDATE: Following customer requests, users can now purchase a Developer License for Microthemer (but only from themeover.com directly – CodeCanyon doesn’t offer Dev Licenses at the moment, and the Extended License is too expensive (in my view) and doesn’t permit use on client websites)
Microthemer is a feature-rich visual design plugin for customizing the appearance of ANY WordPress Theme or Plugin Content (e.g. contact forms) down to the smallest detail (unlike typical Theme Options). For CSS coders, Microthemer is a proficiency tool that allows them to rapidly restyle a WordPress Theme. For non-coders, Microthemer’s intuitive interface and “Double-click to Edit” feature opens the door to advanced Theme customization.
