First, a little history.
Since Vista, I've used sidebar gadgets, and do the same with Windows7. I won't do without them anytime soon. What I missed, however was the actual sidebar to dock the gadgets on.
Enter a gadget that does just that, called 7 Sidebar. I've used it since Win7 released and it does exactly what it is supposed to do, plus it is skinnable and can show open windows. No crapware, no issues, and gets updates. 100% free!
Now to the good part for you gadget users. The latest update linked me to an app I'm sure all you gadget lovers will find use for in Windows 8.
They now make an app that will let you use your gadgets with Windows 8! (see external link)
Back up your gadget installers or files. You don't need to say good-bye to them just yet!
I can't personally try it as I'm not touching Win8, but I trust this software company. Try it out and see for yourself.
