This is seriously a life saver when it comes to organisation. As a student, I work on different many different projects and assignments. I can keep each assignment in a different window, then send the entire window of tabs to OneTab when I am working on a separate assignment. Without OneTab, I would have windows cluttering my dock which would distracting me and suck up computer power.

I also really like that you can name and share tab groups. Sharing tab groups comes in very handy when I am using more than one computer to work on an assignment.
