businessbox

Global Content by BusinessBox allows you to define at only one place some content globally used all over your website.
Hence it prevents from writing mutlitple times some hardly-maintenable text.
Plain text as well as more complex HTML/CSS code can be put in each of those global variables.
Simply use this content in either your templates by using our PHP function <code>gcbb_get</code> or directly in the content of posts or pages using a modifiable tag such as <code>[GCBB#variable]</code>.

Define only once some global content and reuse easily in templates and posts/pages as many times as required

Alex Prokopenko / JustCoded

This plugin allow you to create simple text variables (single/multi-line) to use them in your theme templates after that. 
Once you added at least one variable, a new page called Theme Variables will appear under the Appearance menu. 
You can move all your text data (like copyright text, phone numbers, address etc.) to variables. 
So if the final client wants to change this text, he can do this easily as admin without editing the template.
This project is also available on github.com: 
https://github.com/aprokopenko/justvariables.
You can post issues, bugs and your suggestion in Issues tracker there.
