There are many available tools to help make Web Development projects quicker and more productive.
We will look at how a Magento Web Developer can help increase productivity, to turn on or off those common features all from the front end of Magento while developing on a site.
Magento Developer Toolbar
Magento Developer Toolbar is a powerful and must have plugin to any Magento Developer that lets you quickly access regular used functions without having to keep multiple tabs open with the admin backend
By using this plugin we can measure the performance of the site and see what is happening in the background such as database queries or which events or observers are called further optimising the Magento store as we will only choose what want to call rather than calling unnesseary events which may lead to less performance.

The plugin itself sits on the top right of the page, showing key page statistics on a per page basis and is unobtrusive and can be expanded to show more detailed statistics to aid further web development.

Using this plugin has enabled us to continuously review a Magento site performance by only calling what is needed aswell as speed up the Magento development build time.
