It’s experiment. By GP is often done GUI in UPBGE for games, so why not?
My vision by script was in way that the whole frame can be scaled and divided (A,B,C 1,2,3… etc) by needs, tables can be filled by addon, and the frame + txt can be tinted by colours (eg. white, black).
Due “pined” layer to front camera user can operate viewport with measure descriptions as want.
Regarding multiple divs… it’s more compliate as job for composition.
