I have a programming background and have looked at your source .lua files.
Not having a good foundation in Lua programming, most is understandable through examination but understanding is not quick.
You must have program statements that resize the viewport. I should be able to edit my nui.lua file and change the port size. I've not been able to find such a statement but am sure it exists.
Please correct me if I'm wrong. I still search for such a line.
Thanks,

P.S. Yes, I have a stubborn streak "a mile wide".
