I use https://github.com/nsf/gocode in conjunction with https://github.com/Shougo/neocomplete.vim for my Go autocompletion.

It works really well, except for one little thing. When I type something like fmt.pri I get autocomplete option like so:

fmt.Println(a ...interface{}) (n int, err error)

Since I'm new to Go, this is super helpful, because now I know what arguments the method takes, what are the types, and also what does it return. Unfortunately, as soon as I write past bracket, the information is gone. fmt.Println(

So on more complex methods that I'm using for first time, I'm stuck, and have to jump to source definition, or run godoc.

It would be much easier to have that information available somewhere, preferably on the bottom of Vim where the command/status line is.

Does anyone know how such a thing could be achieved?

EDIT: Preview window breaks my Vim so its not an option.
