Essentially this is a small webbased tool which will allow us to annotate the web document with pen(freehand pen tool) and write notes (like sticky note). We already have a working prototype at [url removed, login to view] (You can find the screen video at [url removed, login to view])
We would be mostly using this tool in the Firefox. This means that developer can use Canvas ( [url removed, login to view](HTML_element) .
As a developer you would have got the idea from the working prototype, however you need to ensure following
* Annotate any page length webpage
* Add/Remove/Edit any annotation objects (Pen and notes)
* Quick response time to mouse movement (working protoype lacks this)
