I can't help you there, The Scyphozoa, because I only used the code from Turbine, except of course the ID-tag bug.
After that I repositioned and resized the system and bag buttons and positioned the main bar according to my 1600x1200 screen resolution
Haven't really done anything else
I added a comment in the XML which points out the position. So if there would be any positioning issues. I can direct people there
