Good question.  My vision is a UI similar to mc with directory listing in one 
panel, file content in the other panel, “quick view” and “lynx-like navigation” 
switched on.  Help keybindings <h> <?> will become superfluous, and keybindings 
<Tab> <Ctrl-i> to switch focus between menu and help “panel” will be added.  
Implementation will require some ncurses exercise and more time, than I have 
available in near future.  Thus I keep saying “no promise …”
