Rule of Thirds Overlay on Selection Area

[WicksterZero]

Hi, I've purchased XnView quite a long time ago and I have to say it is by far the most used application in my workstation. I also run Photoshop for my everyday photo editing needs and there is a process that I would like XnView to take away from PS. It's kind of a hassle to run Photoshop to crop images when XnView does it faster and more efficient. However, PS has added the Rule of Thirds overlay on their crop tool and it makes cropping really nice. So I was wondering if XnView could add a similar overlay on its selection area to greatly enhance its cropping tool?

I've attached a quick mockup.

thank you very much for taking the time to read this and have a wonderful day.
