So including files in a buffer list?  Seems odd, but then ido
had a lot of oddities.

Anyway, I think what I miss most about Ido also solves the
problem of going to recently visited files.  In Ido, I could
ido-find-file, type a fragment of a file name and then M-p to
cycle between those old files that match that pattern

In vanilla completion, icomplete, etc (and this includes fido-mode),
M-p doesn't do this search.  The workflow for this appears to be M-r
for previous-matching-history-element but that asks me to input
a regexp, which is not necessarily the completion style I have
configured.  Even when I do that, it doesn't seem to work very well,
doesn't seem to go into the recentf list, or at least is confusing
enough that I don't bother trying it.  But I still miss that feature
after many years away from Ido.

So, if I were to work on something for Fido, it would be that
feature (which, importantly, doesn't mix buffers with files in
the same bag).
