Re: Repeated call of customize buffer returns error

[Richard Stallman]

    If the mail buffer is not yet displayed, it would behave just like it does
    now.  And the mail buffer is already displayed somewhere, it would select
    that window instead of switching the current window to show the mail buffer
    a second time.
    Sounds like an improvement to me,

C-x m is supposed to switch to the buffer in the selected window.
Like C-x b.

Would you like a feature that all such commands would
select a different window when the buffer is visible there?
That might be an ok feature to have as an option.
