You can save all of the tabs of your current session as a bookmark folder in one fell swoop! Your research tabs can be all saved together and opened as a group! Your gift ideas that you won't close because you don't want to forget about them can be saved in a folder named gift ideas so the next time you need them you have them, without the cost of using up your extra RAM and CPU cycles!
I remember both Chrome and FF making a big deal over that point years ago.
