yes, it occurred to me a few minutes after sending the mail...

Yes. I see that now. And for the "append" option that is particularly
unfortunate (but changing the default to "custom" does not help at that point,
either; quite the contrary: If you first check "append" on the first tab, then
select "CSV" on the second tab, you may be in for a nasty surprise!).
Have you tried moving all format options to the first tab? Perhaps moving
encoding to a less prominent place?

Yes, neither alternative is clearly superior to the other. But on the other
side of the coin, listing all these parameters makes it harder to see just
what you changed from the default.
Besides, this still does not explain what other values are permissible for
each argument. Particularly for parameters with non-obvious semantics, such as
col.names (and I don't think anyone would guess the correct meaning of
col.names=NA without consulting the documentation).

Except for "quote".

Simple: Just like any standalone plugin (including a <dialog>).
The additional thing to worry about is "passing information" between embedded
and embedding plugin. The standard ways are:
1) Providing <external>-properties in the embedded plugin.
2) Generating code the usual way. The embedding plugin can retrieve that using
Oh, one more thing:
- The export plugin's .js code still lacks appropriate i18n()-calls. Consider
utilizing the new Header()-functionality to make that easier (http://firstname.lastname@example.org/msg02499.html).
