NOTE: the "HeadsUpDisplay" moniker is going away soon for L10N reasons among others. | |||
Create an interactive Console to help web developers understand everything that happens during the creation of a web-page. Console entries will be time-stamped objects representing errors, network traffic, javascript events, DOM/HTML mutation and logging output. The Console will also have an interactive command line for evaluating javascript against the current webpage and an interactive Workspace window for entering and evaluating larger blocks of code. | Create an interactive Console to help web developers understand everything that happens during the creation of a web-page.

== Top Features List == | |||
''' | '''TOP 5 Features [IN FLUX] - (all else is secondary)''' | ||
*1. Logging of tab-specific activity | |||
*2. Deeper inspection of logged data: clickable/inspectable objects | |||
*3. Interactivity in console: command line commands: find, inspect, pprint, etc... / console input expands/shrinks based on user input | |||
*4. Console->Inspector, Inspector->console communication | |||
*5. Console Snippet Editor: keep code snippets around for later editing and execution. (robcee will give a smalltalk demo that will inform this idea at the summit) | |||
