Replaces the default text in the Debug Bar button (which is “Debug Bar” by default in English) with the page’s query count and total sql time. The button will be red if there were more than 200 queries or they took more than 1 second to run, and orange if the page required more than 100 queries or took more than 0.5 seconds to run.
Requires the <a href="https://wordpress.org/plugins/debug-bar-console/" rel="ugc">Debug Bar plugin</a> and for the constant <code>SAVEQUERIES</code> to be true.
Inspired by the Admin Bar on WordPress.com VIP, which offers similar functionality.

Debug Bar Query Count Alert

A simple add-on for the Debug Bar plugin to replace the button text with the database query count and time.

BlackBox is symfony like unobstrusive debug bar attached to the top of the browser window.
How can it help you with development: 
1. instantly inspect global variables (GET, POST, COOKIE, SERVER) 
2. debug both frontend and admin area 
3. executed MySQL queries and time it took to execute each query (useful for finding slow queries) 
4. profiler for measuring performance of your plugins and themes 
5. errors occurred when loading WordPress page

BlackBox Debug Bar

Immediate feedback on a great majority of errors. Added a conditional red background to the Errors, and with this modification I have never miss even a notice anymore.

Thank you very much!

Essential plugin in my developer toolset

BlackBox is a plugin for plugin and theme developers. It collects and displays useful debug information (errors, executed queries, globals, profiler).
