Can you add separators to Docky?

Is it possible to add more separators to Docky? If so, how? I've checked through the preferences window but I didn't see anything about adding separators there.

No, you can't add separators in Docky.

The developers have said that this feature is not planned for future releases either.

Robert Dyer said earlier this year in response to the question "How do you Add a Separator line?":

You dont. There is no way to add these yourself and no plans for such a feature.

He went on to explain:

Docky is all about simplicity. Being able to add separators gives you no new functionality. You can already arrange/group launchers however you want. That little bit of separation between them really doesn't give you anything worthwhile and we try to keep the feature set somewhat small and not present the user with too many options (we pick what we feel are the 'sane' options).
