This isn't going to help directly with the transposition process, but might help to keep track of things. I have a little screen capture pgm that I use for a number of things. I particularly use it on this forum to copy posts that explain how to do things so that I can look at it whenever I need to find some help on something. You could capture a screen in chord view before and after changes to keep both available. The pgm is free and called "prtscr". I save the images as .jpg.
