Absolutely I want it!
In fact a few weeks ago, I surveyed the seat sites looking for one that had actual window locations and was overjoyed that Seat Expert had them! I almost decided to make it my primary seat site, but didnt for a couple reasons I dont entirely remember right now, but I do recall I wasn't 100% confident that the window positions were entirely accurate. However, I think I verified the positions on the 757 where it is especially important since there are some missing windows, and found seat expert to be fairly accurate. I intend to start referring to it more often now.
Thanks!
