Opera has long supported Multiple Document Interface (the ability to display multiple document windows within the main program window); in Opera 4, a Windows taskbar lookalike lets you switch between pages by clicking a button.

The drawback is that Opera 4 supports, but doesn't ship with, Java. You can only add this via a free plug-in from Sun (java.sun.com/products/plugin). And Opera isn't free: after a 30-day evaluation period, you have to pay $US39 ($US15 if you're an upgrader) to keep it. Given that the competition is free, price may prove the most formidable barrier to widespread acceptance of Opera 4.
