excellent job. I only find the light blue background too bright and modified your 6field dashboard a little bit by changing the background to transparent grey.
Unfortunately the transparent grey png's are much bigger than the original files and GIR-Editor does not manage to compress the files to keep the original file size.
Nonetheless the dashboard works on my 3590 with only the landscape background exchanged but not with the portrait image additionally changed.
I enclose both background files in case someone wants to finish the job. TIA
