With UTabs, you can save as many combinations as you want and open them again whenever you need. The only thing you have to do is open the extension from the Chrome navigation bar and save the tabs. The tabs will be automatically saved according to the date and time, but you can also change the name of the grouping to whatever you want.
This way, you can give your device a break. You won't have to automatically open all of the predefined tabs in your browser, and you can reopen them only when you really want to.
The extension also lets you search the different groupings of tabs that you've saved.
