I have to use #chrome  at work, so I get excited about time saving features. Chrome has been able to create "tab groups" for some time. Right click on the tab and make a new group, then drag and drop to add tabs. 

But in their experimental features there is the ability to *save* these groups, so you can make one for each project and call back all the windows you need with one click. 

chrome://flags then search for "tab group" and enable it!

It's creepy how organized I am this year!
