Clicking on the title bar when I want to expand a half-window to full width of my screen works every time, but clicking on it again to return to the previous size sometimes works and sometimes not.
Sometimes when it does return it to the previous size it switches it the opposite side of the screen from the side it had been on. I haven't be able to figure out if there is some purpose or pattern to this, or if it's just a bug.
Another thing that is inconsistent is when it opens a new private window as a new half width window. I like that it does that if the active window is half-width, usually on the same side of the screen. However sometimes it opens it on the opposite side for some reason. Again I haven't be able to figure out if there is some purpose or pattern to this, or if it's just a bug.
