Yup.  I sure wish some more UI folks would get involved.

I don't understand this. What were you doing?

Hm. That's odd and bad.

It would be good to submit issues for all of these:

No, they don't.  They are both about constaining the containment relationship,
from different ends.

Not sure what you mean.  Are you talking about places in an installation,
or in the repository?

You can, but it probably means something else than you intend.

One problem we have is that, in many places, we mix definition and
configuration.  For example, in a page definition, we define a component,
and we say how to do it.  I'd like to have a way to separate these, so
you can, for example, define a page once and register it as many times
as you need.

Sure, with tha caveat that much of the interesting information, like
what adapters are available, is installation specific.
