  This chrome extension is to help anyone who is has trouble remembering why they opened a tab! This could be for many use cases, such as if you left your workspace for a moment and then came back to it, only to completely forget why you had this tab open! 
  
  Before leaving your workspace you can simply start a reminder, with a timer. If you come back to the tab before the timer is done, then nothing will happen and it will assume you remember why you opened this tab or why it exists. Otherwise, it will show a popup at the bottom of the screen with a reminder that you added. 
  
  For example, let's say I randomly open up a tab because I'm interested in researching something just for fun. However, all of a sudden I have to step away from this tab temporarily due to some distraction. If I know I might forget why this tab existed or completely forget the existence of this tab, I can put a reminder. Let's say I know that I'll be free again after 10 minutes, so I put the timeout at 10 minutes. 
  
  If I come back to the tab before the timer is up, then it will not show the reminder popup. However, if it's been an hour or a couple hours, and I come back to it(likely confused at this point), then it will show a popup at the bottom of the screen with the reminder I inputted.

  Never forget why you opened a tab again!
  
  What Was This For? lets you attach a reminder and timer to any tab before stepping away. If you return before the timer runs out, nothing happens, and it will assume you remember. If time's up though, a popup appears at the bottom of the screen with the reminder you left for yourself.
  
  This is a perfect tool for when you open a tab to research something, get pulled away, and come back completely confused about why it exists.
