TidyTabs is a tool that allows you to free up your desktop or organize your applications into tabbed groups for easier and quicker access. Ever wanted to have Chrome-style tabs in Windows Explorer, Microsoft Office, or PuTTY? TidyTabs does just that. It integrates nicely with the OS and you will feel like the multi-tab functionality is a core part of Windows. Once TidyTabs is running, it will automatically tab-enable any application. The tab will appear when you hover your mouse over the top left corner of the window. Even if you have different apps open, like Excel, Word, and PowerPoint, you can use TidyTabs to create a single window with each program in its own tab.
