I'm so glad it's proved useful for you! Entirely unrequired, but I'd be curious to see anything you used it in, just out of personal curiosity and enjoyment of retro-looking UIs.
I’ll update you when I’ve actually got a UI going. I’ve got an RTS game project where the current UI direction is like the old tycoon games (railroad, roller coaster, open ttd) so this is right on the money for that.
