Usability enhancements for The Housing Bubble Blog (http://housingbubble.blog)
The Joshua Tree Extension adds usability enhancements to assist in reading Ben's Housing Bubble Blog, including:
* Tracking/identifying new comments
* A navigation toolbar for jumping to the next new comment
* Ignore list
* Comment editor enhancements, including preview functionality and HTML validation (no more unclosed tags!)
Version 4.0.0 adds partial support for the new blog format, limited to new comment count on main page, and toolbar + new comment navigation on comments page.
