Well, what about it? You move the point to an identifier. Its
signature and a few lines of documentation are shown in the echo area.
You invoke (eldoc-doc-buffer) and see the whole documentation.

It may be a bit inconvenient that the content of that buffer changes
as you move point to a different identifier. But that can be worked
around with (clone-buffer).
