I have recently caught up with a strange habit. Closing the window by double clicking on the top-left most corner.
Usually I started doing this whenever I am closer to the left hand side of the screen. Hope you knew that you can close the window from top left most corner ! Try the single click on the leftmost corner and you will get this.
This lead me to a crazy idea (or might be a shitty idea as well !)
There’s ample space left on the top-left corner of the window, so why not keep the good-ol 3 buttons there as well?
Or even the mirror image of the right hand side. Close | Max | Min
