Simon WP Framework has been updated. Currently, we are working very hard to make this WP Framework the framework of choice with designers. There are other frameworks, but not many are really free, responsive, and flexible.
The main improvement in 2.0 is responsive design and the addition of Media Queries. This is only a start and there is an update coming soon. Then we will update WordPress once the dust settles. Thanks for the support and enjoy Simon WP Framework.
