Re: [RTW] My biggest concern

In my own situation, I have a list of common viewed websites at the top of my browser and a simple accidental click will go to those new pages.

If that's your biggest concern, then I have good news for you. Firefox 4 has a feature called App Tabs designed to address these use cases (I believe Chrome has something similar, but I don't use it so I don't actually know). More information here: http://support.mozilla.com/en-US/kb/what-are-app-tabs, but the relevant sentence is: "Links to new websites open in a new tab so that your App Tab doesn't change." I think this does exactly what you want. In any case, this is fundamentally an issue for the user-agent, and not, I think, one that has much impact on the actual standards.
