Enable posting of unfiltered HTML in a Multisite environment, configurable on a per-role basis.

This plugin allows blog administrators in a Multisite environment to specify user roles which are allowed to create posts with unfiltered HTML. These users will be able to make posts containing <iframe>, <embed> etc without that content being stripped by Multisite's sanitisation rules.

The plugin can either be used globally for your entire network, or it can be applied on a blog-by-blog basis. Regular WordPress already allows this feature and does not need this plugin. (more)

Configure access to the admin backend on a per-role basis.

A very simple Wordpress plugin that allows you to disallow access to the admin backend on a per-role basis. Mainly you would use it to prevent subscribers from being able to get into their backend 'edit profile' screens.

Browser-level device detection and theme switching. Compatible with all caching layers.

A JavaScript-based mobile theme switcher plugin for Wordpress, brought to you by Map Creative.

The chief purpose of this plugin is to allow functionality similar to Device Theme Switcher, but without requiring the use of any serverside logic. This allows the plugin to function where others would fail, i.e. in server setups with complex caching mechanisms sitting in front of Wordpress like a Varnish layer or WPEngine's EverCache.

A selectable state persistence mechanism also features, to allow for mobile theme state to be passed by URL or other methods for greater compatibility with complicated caching layers (more)
