For WordPress Multisite (WPMU) installs, allows Super Admins to easily manage each users roles and blogs from one 
screen in the Network Admin menu.
You no longer have to go to each blog to change the user’s role. It’s also 
much easier to see which sites a user is associated with.

Multisite User Role Manager

Ajax management makes it super easy to add users to a bunch of sites in the network. Does 1 things really well, more plugins should work like this.

Great for multisite user management

Made adding a user to 20 sites a lot easier than using WP's default interface for that (way less clicking around).

Much easier to assign a user to many sites

I spent about 30 minutes looking at different multisite user management plugins and all of them were either out of date, or tried to do too much. This plugin solved the exact issue I was dealing with: adding a user (with a specified role) to all of my client's subsites. 

Thank you very much. 

I wish you all the best,
Kevin.

P.S. the CSS for the admin screen where you add users to subsites was a bit off for me (in Chrome). The table did not fit the modal background (it hung off to the right a bit, and forced me to scroll even though there was plenty of vertical space). It doesn't bother me but it might bother some other users so I figured I would let you know. 

Excellent plugin - it does what it says!

With <a href="https://layered.market/plugins/if-widget" rel="nofollow ugc">If Widget</a> you can control on which pages widgets are shown. Show or hide widgets with custom visibility rules (no PHP or technical knowledge required).
The plugin is easy to use, each widget will have a new option “Show widget only if” which will enable the selection of visibility rules (example in Screenshots). Visibility rules can be combined with <code>AND</code>/<code>OR</code> to create even more personalised visibility options.

<li>Display a widget only if User is logged in</li>
<li>Hide widgets if Is mobile device <code>OR</code> Visitor is from US</li>
<li>Display widgets only for Admins and Editors</li>
<li>Hide Login or Register widgets for Logged in Users</li>
<li>Show widget only for Admins <code>AND</code> Is not mobile device</li>
</ul>
<h4>Visibility Rules</h4>
These are the visibility rules you can add for widgets:
<ul>
<li>User state: <code>User is logged in</code></li>
<li>User role: <code>User is Admin or Editor</code> (plus all the available roles)</li>

<li>Post type: <code>Current post type is Post or Product</code></li>
<li>Page type: <code>Current page is Front Page or Blog Page</code></li>
<li>URL: <code>Current URL starts/ends with "this-page"</code></li>
