Hmmm, I missed that one, I think...

One reason could be that I simply don't understand some aspects of
z3c.form/macros etc. For me, it was so complicated in my non-generated forms
that I rather invented something on my own.
Another aspect for me is, that I personally don't like macros so much, with
these "widget snippets", I hope, I can avoid them in my application. For me
macros tend to be complex ("unübersichtlich" - I think there's no direct
translation for that german word?), and I don't see how they would work well
in the case when I don't use generated forms but arrange the widgets
manually. Probably I would need an extra macro that acts as my "snippet"?
So, in my snippet-way, it looks like that for every widget:
<span replace="structure view/widgets/mywidget/snippets/foo" />
And in the macro-style? Perhaps like that?
<span metal:use-macro="snippets/foo">
<span metal:fill-slot="snippet">
<span replace="structure view/widgets/mywidget/render />
</span>
</span
This is boilerplate code I'd rather like to avoid. Moreover, I can register my
snippets on specific widgets and also on specific modes. In my case, I could
probably use the same template for input and display widgets as I simply
register one snippet for input, and another for display.
In case of macros, I assume I'd have to rewrite my template, as I have to use
e.g.: "metal:use-macro="snippets/foo_input""
and "metal:use-macro="snippets/foo_display"".

Well, that's certainly a possibility. Currently I'm
implementing "Form-Frames", which complement snippets by adding surrounding
template code, such as <form>, buttons etc., let's see...
