Windowed Mode needs Borderless Window Option

Just as the title says.

I don't understand why you guys would give us Windowed Mode WITHOUT implementing "Borderless Window".

We wanted Windowed Mode so that we could Alt-Tab to get information (since the game does not provide it to us very well, we need 3rd party websites like ffxiclopedia).

However, Windowed Mode has a huge border around the window and I can't move the window around very well. Most games have a "Borderless Window" option that is basically fullscreen, except you can alt-tab without minimizing the app to a taskbar button.

Could we please get this sometime soon?
