Is there a tool to do the "meaningful transition". I like the ability to
design the content type schema TTW, but I haven't got a button to export
it (b2 + plone 3.3.5).

I found this...

"""The type definition can just be exported via portal_setup by exporting
the types tool. We want some new UI for this. The schema will be in there,
in escaped xml. You can also put this in a separate xml file, or define a
zope 3 schema--use plone.directives.form for this."""

Also, is there a roadmap / vision. I used Dexterity earlier this year and
loved it. But that was a standalone way to get grok to build a form with
complex functionality. The TTW tool potentially gives the ability to
customise classes built using dexterity. It is really cool.

These are all valid problems. I don't want to discuss them, because I am
not advocating TTW. But I will point out that I worked around them all
when doing TTW, e.g. APE allowed me to keep Code in SVN, multiple Zope
instances allowed me to develop different branches, my data was in
Postgres anyway etc.
