Toolbox for Windows 8
Metro’s designed for full-screen apps; if you want to cheat, you can snap a sliver of a second app onto the side of a reduced full-screen app -- but that’s it. Toolbox for Windows 8 gets around that by putting up to six apps on the screen simultaneously. You can choose from 11 offered apps -- even fill different slots with the same app, with different settings, so you can run Clock apps in different time zones, or browser apps that run independently.
I had some stability problems, but there’s much to be said for the ability to take notes in a meeting while simultaneously looking at your Facebook page and running the countdown timer.
Toolbox for Windows 8: Free; Notes app is $2
