Command your admin dashboard. Manage built-in widgets (Right Now, Recent Comments, etc.) and dynamically registered widgets (Google Analytics Summary, WP E-Commerce Dashboard, etc.). Hide widgets depending upon user capabilities.
This plugin is based upon Dave Kinkead’s Dashboard Heaven plugin and extends it to support dynamically registered widgets, such as dashboard widgets that are added by a plugin.
After installation access to all dashboard widgets is removed, then you can use the options at Settings > Dashboard Commander to configure the minimum access level for each widget.

Show the world how you use the command line with this plugin. Designed for tech blogs, tutorials and sections 
where terminal commands matter.
This plugin, make a shortcode: [simterm][/simterm] and shows the text inside as in a terminal session, including 
some typing animation and separating user input and program output. 
By defaults commands have a $ symbol as the first character of the line and user input has the > (greater than) 
symbol.
You can also specify the color of the line using ##red## , ##blue## , ##green## or ##yellow## or even a custom 
delay for this line with ##delay=[ms]## with the amount of milliseconds to sleep.
To create the effect it uses “Show Your Terms” by Kande Bofim, a tiny and library agnostic Javascript.

SimTerm

Make demos of your terminal commands and output in an attractive way.
