Please restore the "Portfolio" page.

It was very convenient to be able to scan the list of new articles related to my portfolio, and to open on new window/tab (without losing my place on the list) when I clicked on one of those articles.  With the changes you've made -- because each article opens in the same window (not a new window) -- I keep losing my place on the list.  After clicking on each article, I now need to spend time searching for where I left off.
