Why there isn't a button for clearing the crashed windows yet?

This is my third topic opened, and this is the main reason why I opened all these topics. First of all let me tell you, I was in so much pain trying to delete 1000+ of crashed windows in the tabs outliner. I am not kidding, if you think that I am, I will be taking it as a personal insult.

What I have done to get all of them removed was to remove tabs outliner and reinstall. When ever I am forced to reinstall something, I consider it as a bug, and I think this is only fair.
