Hi Philip,

I think this added sentence is not clear.
Also, no documentation for these special properties for toggling themes?

This docstring is incomplete.

I'd say: "Command to switch..."

I think that theme writers who care about this functionality will add
:kind and :family to the themes, and those who don't won't bother with
that. So I don't really see the point in supporting (:kind nil).

This message will be confusing when there are themes whose :kind is not
color-scheme...

toggle")))

This will pretty much always error with themes that don't really care
about toggling (see above). Could you tell more about what is the
benefit of supporting (:kind nil)?

Full stop missing.

In the Autoload section of the Elisp Manual, we have this:
"The forms which are not copied verbatim are the following:..."
Shouldn't deftheme be added to that list as well?
