I’ve just gotten a new iGoogle page that supports expanding widgets to full screen on the Google homepage and has a navigation bar on the left for quick access to all gadgets.
As it turned out , this event was
planned by Google
for a long time , and this Google homepage
could be used before others. For this event, Google prepared thoroughly and
released an updated GReader'a gadget that supports full-screen scanning (canvas view).

In addition, there are already many other
"improved" gadgets . Now those users who are inconvenient to keep the GMail and GReader windows separately open will be able to use them without leaving
one page .
Also in the innovations they promised to add a GTalk contact list in the left pane, but I didn’t notice it myself :(
