Visual Feedback for browsing

I like to control my browsing work flow. When I am reading a site with a link, sometimes I want to make sure that the new link is viewed in a separate window, so that I can go back and forth.(Partly this is due to the network speed being not infinite, that's another story). So this advanced user behaviour should be supported by the web site visited. How about putting visual indicators around links that will open up a new browser window vs those which do not. For example, a little icon indicating "additional window". Similarly, required fields on forms should have visual indicators.

Back to network speed, how much of my (and others) browsing behaviour is based on the network speed being not fast enough? How much of the current theorys and studies will go out of the window after boardband?
