Nice! Works automagically with helm which is also nice.

It irritated me though that the current tab is not a member of
the list.

Therefore with only one tab the list is empty.  If one then hits
RET on this empty list, there is an error message:
"funcall-interactively: Wrong type argument: number-or-marker-p,
nil".

I now see that an unconfigured emacs also does not show the
buffer from one called switch-to-buffer.  helm-mini which I
actually use, shows the the buffer you worked in when callin
helm-mini as a possible last target of the listed buffers.  This
seems more natural to me.




Ciao; Gregor
