Silently prevent duplicate Gravity Form submissions.
This plugin adds silent duplicate detection to the popular Gravity Forms WordPress plugin. The goal is to prevent Gravity Forms from creating multiple entries when an impatient user double-, triple, or full-on secret-combo-move-clicks his/her mouse when submitting a form. No modifications to your forms is necessary, it just works.
Plugin development can be tracked on the project's Github Page: https://github.com/buckii/gravity-forms-duplicate-prevention
