NOTE: THIS PLUGIN WILL ONLY WORK WITH REDUX BASED THEME.
There was a big problem in Redux based themes.
BIG PROBLEM: If more than 1 users working on a site and using Theme Options, and tries to save their changes at the same time, only one user changes will be saved and other 2 will loss their data completely from Theme Options (overwritten behavior or workflow conflict issue). This creates lots of headache during site or theme development.
SOLUTION: We just found the solution and develop plugin for Redux Based Themes users. If USER1 is already working on theme options and USER2 open theme options then his Theme Options screen will be lock by Popup just like WP Page/Post editor handles this.
