Panelize fixes one of Chrome OS's fundamental flaws
Chrome OS does support one way of displaying multiple Web pages at the same time, however: panels. If you've looked through our Chromium OS galleries (or taken a quick look at the screenshot above) you'll notice some always-on-top panels across the bottom of the screen. Panels are handy things -- capable of being resized, or quickly popped down out of view. By default, the download manager, popped-out Gmail chat windows and the media player display in panels -- but, for some reason, there's no way to load custom websites in panels.
Which brings us onto our very first Chrome OS-specific extension: Panelize. With Panelize you can put anything into a panel, such as Gmail, Reader, or even Download Squad. In one fell swoop, having to switch between tabs is a thing of the past!
Realizing that full-size websites don't look very good in small panels, Panelize lets you pop open mobile versions of popular Google services, like Gmail, Docs, Reader and Voice. If you look at the screeshot above, you can see the mobile version of Reader in a panel -- pretty darn cool.
To open your current page in a panel, just click the Panelize button and then "Reopen current tab as a panel" -- but be prepared to do a lot of scrolling, unless it's a very narrow website. It sure would be very nice if Panelize let you spoof a mobile user agent for new panels...
