Custom Tweaks for Jetpack by BarryCarlyon

Extras for WordPress Jetpack. Tested up to Jetpack 3.4.1

The <a href="https://wordpress.org/extend/plugins/jetpack/" rel="ugc">Jetpack</a> plugin by Automattic does something sneaky: it auto-activates new Jetpack modules. Instead of allowing you to opt in to new modules, Jetpack cheerfully activates them without your permission. These modules can change how your site works and looks.
Manual Control puts a stop to that unwanted behavior. It prevents auto-activation of new Jetpack modules.

Jetpack auto-activates new modules, without asking your permission. This plugin stops that.
