I dig it!
Nice work as usual.
After you said the door is shorter so the hammock can come out, it seemed there might be a limit to where you can hang (without the hammock hitting the door). I don't know if it would work or how you would implement it but perhaps some sort of vertical slit with extra fabric to 'close' in around the webbing.
Probably not worth investigating but I thought I'd throw it out there.
