16	* ROADMAP
17	*
18	* version 2.0
19	* Replace "Prevent the Jetpack plugin from auto-activating (new) modules" with
20	* finer grained "Select which modules to auto-activate"
21	* see http://jeremy.hu/customize-the-list-of-modules-available-in-jetpack/
22	* function jeherve_auto_activate_stats() {
23	return array( 'stats' );

25	add_filter( 'jetpack_get_default_modules', 'jeherve_auto_activate_stats' );
26	*
27	* TO CONSIDER
28	*
29	* Make blacklist or whitelist optional
30	*
31	* Option to disable JUMPSTART with "Jetpack_Options::update_option( 'jumpstart', 'jumpstart_dismissed' );" ??
32	* or do we need to go through apply_filters( 'jetpack_module_feature' ...
33	* If we want to be able to select which modules should appear in Jumpstart later!
34	*
35	* Can we disable Debug link in the footer menu? No...
36	*
37	* Option to "force_deactivate" (same as blacklist?) as described on https://github.com/Automattic/jetpack/issues/1452
