The Sidebar software is a customizable screenlet that imitates the Vista sidebar. It can be themed to fit your preferences.
To ensure Sidebar functions like a sidebar should, there are a couple of steps you'll want to take. Start by going into the sidebar properties and selecting "keep below" while unselecting "keep above." Then, for all other screenlets, navigate to their properties and unselect "keep above" without selecting "keep below." This way, the sidebar will stay below, while all other screenlets will remain on top but below all other windows.
The only requirement for Sidebar is Screenlets, so if you already have Screenlets installed, you're good to go. Plus, with the latest release, you can now choose to place Sidebar at the bottom or top of your screen. Give your computer an upgrade with Sidebar - your desktop will thank you.
