Do you mean you want to go back to one specific step in "rebase -i",
or you mean you want to go back to the state before "rebase -i"?
If the latter, one nice thing to know may be that "git log -g" is
like "git log -g HEAD@{0}" and inspects the reflog associated with
HEAD, and you can view individual steps of "rebase -i". On the
other hand, "git log -g @{0}" (or "git log -g master@{0}" if you are
on 'master' branch) will inspect the reflog associated with the
current branch, and "rebase -i" appears as a single event (i.e. the
tip before rewinding and replaying all the changes is replaced with
the tip after that whole series of replaying). So the latter is
what you want to use if you are interested in the state before the
whole "rebase -i" operation.
Also you can ask "git log -g HEAD@{now}" and "git log -g @{now}". I
agree with you that "git log --oneline -g @{now}" is very handy, and
"git log --oneline --relative-date -g @{now}" is even better, as I
can clearly see where the flurry of recent activities ends and which
reflog entry is the one I was at 20 minutes ago before I started.

I think I may have answered this part with the above.

Sounds very similar to somebody else is doing ;-)

Agreed to both counts. Thanks for comments.
