Tonight, you can finally get your hands on Deer Park Alpha 2.
With this release comes the now enabled by default "fast back (and foward)" feature which makes moving backward and forward in history blazing fast. We've also enabled the "Reporter" tool for reporting broken websites (you can find this in the Help menu.) In addition, tab drag and drop reordering made it into this alpha release, so did a major improvement to pop-up blocking, and also, error pages have replaced error dialogs.
