Inquirer is a javascript library containing tools for variable inspection and console replacement. It is originally designed to work on embedded browsers without access to developer tools.
Inquirer GUI is based on a separate project but developed together called Merger. Merger mimics a classic desktop environment inside a web page and allow developer to organize GUI elements like windows, buttons, labels and menus on an easy way.
Once inquirer has been included in a web page, is possible to access it any time pressing the famous "Konami Code" (up, up, down, down, left, right, left, right, b, a) By default the Inquirer console will be shown.
