WordPress Database Reset is a secure and easy way to reinitialize your WordPress database back to its default settings without actually having to reinstall WordPress yourself.

This plugin will come in handy for both theme and plugin developers. There are different use case scenarios - one of which is being able to easily erase excess junk in the wp_options table that accumulates over time. Another would be to simply obtain a fresh install of the WordPress database after experimenting with various back-end options.
