Hello, look like a really promising project.

Do you know if it's possible and if it would be hard to provide a way to create native menu like File Edit, etc ?

Something like this : https://electronjs.org/docs/api/menu

maybe even something like dock menu :

I didn't use Qt in many many years but would making the bindings be a hard thing to do?
