FYI, as part of the design work we did for OmniOutliner 4 we did figure out how we would like for cloning to interact with the rest of the feature set, so that's no longer an issue. (And we agree that cloning is useful, which is why we went to the trouble of designing it in the first place.)

But we still think it's more important to get OmniOutliner 4 shipping as soon as possible than to add cloning, so it's still not planned for this release.
