OneTab is indeed a helpful tool if you work with hundreds of open tabs and on multiple windows. Nobody wants to get themselves into a muddle by switching between too many tabs. Also, many times a random web search turns into long surfing where only unmindful things occur. Thus, people lose track of time and productivity, plus they lose the fact of what they were looking at on the web. Furthermore, many professionals' jobs need them to open an excessive number of tabs and connections. Therefore, you can put in a little extra work to clear the clutter and be free with a single click.
