Do you remember when a web browser only enabled you to view one web page within a single browser window and, if you wanted to view another site, you had to open another window. Indeed, go back to Internet Explorer 6 – which is still the browser that ships with a vanilla Windows XP installation – and this will be your browsing experience.

The tab browsing system brought massive changes to the way we access the web. However, apart from having the facility to move around the order of our tabs, they are fairly static. For instance, each tab has its own weighting, so there is no order of preference or tab precedence. If you’re browsing vnunet.com, then any child pages are given the same precedence as the homepage.

Tree-Style Tab Bar is a system that enables you to present your open browser tabs in a different manner, vertically located down the side of your browser window and in a specific order. For instance, the main homepage will be largest tab and pages from that homepage will be smaller, and indented, so you can quickly see they are part of the main website.
