There are thousands of plugin available for WordPress these days. You always have an alternative to every plugin you can think of. I have listed few plugins which you ought to have for any kind of site.
Just after installation of wordpress :
1. WordPress Admin Drop Down Menu.
One of the first things I wanted to improve in the admin area of my WordPress blog, back in the 1.5 days, was the header menu. I wanted to be able to reach any admin page in one click, instead of first clicking on the first level link (”Settings” for example) and then only on a submenu link (”Permalinks“) So came a very neat plugin : the WordPress Admin Drop Down Menu .
All admin links available in a neat horizontal drop down menu. Saves lots of screen real estate. You don’t need to wait for opening parent link then to child one.
2. Anticipate Maintenance Plugin
Anticipate is a maintenance mode plugin that allows you to serve your visitors an alternate "coming soon" page while you work on building your website in the background. Once activated, all of your visitors will be sent to the Anticipate landing page. When logged in as a WordPress Admin, however, your normal theme appears, allowing you to build your website seamlessly in the background.
Although it’s a Premium Plugin yet somehow I managed it to download. Enjoy Freely
An Alternative to this plugin is a theme, freely available on WordPress site http://ready2launch.jedenbod.cz/ (Ready 2 Launch).
