(NOTE: Before saying this plugin is broken, please understand what this plugin does. It’s meant for WordPress installs that have multiple NETWORKS.)
Adds the ability to have different themes available to different NETWORKS in a multisite atmoshpere.
WordPress allows for multiple “networks”, these are not to be confused with sites. A network holds blogs underneath of it.
This plugin will allow you to separate themes into different directories so they’re only accessable and viewable to the networks you choose.
The plugin will attempt to create a directory in the /wp-content/ directory named /ms-themes/. If it fails to create it, then you will need to make one.
In the /ms-themes/ directory you will create a folder for each network that you want to allow only certain themes to.
Example: 
If you have a theme named “Snarfer Theme”, and you want to only allow it to be viewable/available to the network (and all sites on that network) with the site_id of 7, you would place the snarfer theme directory in /wp-content/ms-themes/7/
Future releases:
<ul>
<li>Network option to turn off auto creation on/off network directories, index.php files.</li>
<li>Network option to display network ID in the footer of sites so network admins can easily tell what network a site is under.</li>
</ul>

This plugin works on multisite WordPress installs only.
Use this plugin when you need to add a page on multiple website installs of a WordPress multisite without doing this manually.
You have the following options for adding the page: 
* the list of sites you want to add the page to 
* page title 
* page slug 
* page content 
* set the page as Home, Blog or just simple page 
* set a page template
In case your page already exists (has the same slug) on one of the websites, the page title and page content will be updated.
Useful scenarios for this plugin:
<ol>
<li>create a page in Visual Composer and deploy it to multiple sites in a multisite install </li>
<li>set a page as home in multiple sites in a multisite install </li>
<li>set a page as blog in multiple sites in a multisite install </li>
</ol>
