Singing & Dancing

In the current version (0.9.5) I had to pin plone.app.z3cform to 0.4.9.

the unfair amount of dislikes is probably due to S&D is a quite complex piece of software, very powerful in many different use cases.. people approaching it for "simply sending a newsletter" out of their plone portal could be bitten by it.

still, i found it very useful if you need to solve more advanced cases.

Thanks for the kind words, Maurizio! :-)

I think another problem that people face often is the number of dependencies to extra packages that Singing & Dancing has. This has been a source of frustration in the past, but we have since developed a robust list of dependencies.

Arguably, one has to have a good understand of how Buildout works when using Singing & Dancing. Especially when it's used in larger sites that already have many add-ons.

Singing & Dancing was the first package to use plone.z3cform (in fact, plone.z3cform was developed as part of the S&D effort). And it's probably one of the few Plone add-ons that use zope.catalog.

It would be really nice if you could use a release tool like zest.releaser or jarn.mkrelease to automatically push your new releases to plone.org as well as to pypi.
