Review our app, Boomtango
willwagner: Hi,For a long time, I've griped that the browser history system is old and neglected, but given some love, could potentially be a powerful tool.  A lot of my web searches are for content that I have seen in the past, and while browser history is great for the back button (and the awesome bar), the ability to re-find old content has been sub par.My friend, Alan and I, prompted by the Mozilla Firefox Extend Contest, decided to write a firefox extension that took a fresh look at the browser history system, trying to get past some of the current deficiencies like the lack of 
integration of multiple tabs being open, the inability to monitor ajaxy sites, etc, and being able to do more than search by hostname and date.Boomtango is our rough attempt to put together a system that allows you to search by the content of your page or see your history automatically categorized by it's content. It's all stored locally in a sqlite db, so your web browsing never hits our server.Let us know what you think. We're not awesome ui designers or expert marketers, so any feedback you have, regardless how harsh, would be very enlightening and helpful.Thanks!
