I don't really have a way to do that but there is a neat thing about tablets. You can find and use other pieces and they keep the tablets look, I've done this with another HoTT window and it works just fine. I had to size it to suit me but that much I know how to do.
I feel kinda dumb but I guess I've taken tablets too much for granted. For the life of me I can't picture how that window even showed con, I know it did, but I can't bring to mind exactly how. I THINK it was just a ring around the outside of the green square but I can't swear to it.
Personally I think you've done enough, more then enough, for me as it is. I can deal with the window I adapted
