No, but I'll see to it that they are.

Correct.

I'm working on this right now - should be no big problem.  A few minor
incompatibilities with our current outline.el need to be addressed, but
I'm working on them.

No; I'll try to get this in.

Won't all happen overnight, but I'm getting to work on it.  I very much
appreciate your willingness to help!
