While I certainly agree with you that whoever wrote the Overseer window needs more education, and I've been enjoying reading about your progress and even learning a few tricks from your thread here and your UI code... it appears they haven't learned.
The test patch changes for the extended target window are even more frightful because they didn't even make elements in the xml for us to move or resize, and playing around with it to try to figure out how it's measuring the new 'target con ring' thing is proving very tedious and unsuccessful... at least for me.
