I really have no clue if this would work on 3.8, sorry.. I'm not assuming it will since the structure of 4.0 is so much different. The login across the top is set like this in the 4.0 version. I guess you could try installing it and see what happens, preferably on a test board ofcourse. If it doesn't work, see if you can tweak it or otherwise delete it..
Let me know if you need any help. Glad you like my design
