perkymbf.el

perkymbf.el makes your Emacs use a dedicated minibuffer frame that becomes visually highlighted whenever it is prompting for input. I found this helpful on a large computer display with multiple Emacs frames.

The above old animated GIF shows a tiling window manager with 3 normal Emacs frames, plus a separate Emacs minibuffer frame, plus a Web browser. A thin yellow border shows which X window has keyboard focus. The minibuffer frame is shared by all the other Emacs frames. perkymbf.el is turning the minibuffer frame yellow whenever any of those Emacs frames is prompting for input.
