 * Hi team, thanks for this great plugin.
 * On Google PageSpeed insights we are seeing 2 warnings:
 * 1- Avoid serving legacy JavaScript to modern browsers warning for: `/plugins/
   super-socializer/js/front/combined.js` file: …front/combined.js:1899:3883
    [@babel](https://wordpress.org/support/users/babel/)/
   plugin-transform-classes
 * 2- Reduce unused JavaScript for
    /tr_TR/sdk.js?hash=4bd2f8e…(connect.facebook.
   net)
 * Are these expected / could there be any solutions to these in the future releases?
 * Cheers,
    Reha

 * Similar question, gtmetrix shows message “unused javascript” on object – [https://www.mydomain.com/wp-content/plugins/super-socializer/js/front/combined.js?ver=7.13.30](https://www.mydomain.com/wp-content/plugins/super-socializer/js/front/combined.js?ver=7.13.30)
 * It is enabled sitewide not only on the pages where plugin is directly used, is
   there any way to disable it where loading this object is just a waste of time?

 * Unused js issue is resolved for our homepage once I unticked the two below checkboxes
   under General Options:
    – Include Javascript in website footer – Load all Javascript
   files in single file
 * However would still be good to hear about the following from the developers:
