Hi David,
for people starting out with TW it is probably pretty confusing since
the documentation states that the toc macro expects the first parameter
to be a tag and not some weird half finished filter expression.
Obviously using that trick yourself is totally fine for all practical
purposes, it was merely a side note for Jeremy (and others) that those
filter injection tricks are not user-friendly for new TW users but when
people tend to do this to get more complex behaviour out of a macro,
they will inevitably get in touch with this and it will be very
confusing for them.
On the other hand, please don't ruin this beautiful macro by adding
useless parameters :D

I am curious why you say it will not make for a good end-user
experience whatsoever, since the end result of the toc will be the same.

Hi David,
the toc macro does not actually accept a filter expression as its
first parameter, but instead just a tag that is then filled into a
filter expression. Within the toc-macro, the list widget is
invoked with the following filter exp:
<$list filter="[tag[$tag$]$sort$]">
$tag$ is the first parameter, so your
<<toc-selective-expandable '[tag[GettingStarted]!tag[$:/Note]]'>>
leads to it being filled in like this:
<$list filter="[tag[[tag[GettingStarted]!tag[$:/Note]]]]">
And this is obviously not a well-formed filter expression. However
this is not the end of the line. To make
your filter work, you can do a filter injection by doing
<<toc-selective-expandable 'GettingStarted]!tag[$:/Note'>>
so that it becomes
<$list filter="[tag[GettingStarted]!tag[$:/Note]">
which will work but doesn't make for good end-user experience
whatsoever.

Why would both this:
<div class='tc-table-of-contents'>
<<toc-selective-expandable "[tag[GettingStarted]!tag[$:/Note]]">>
</div>
and this
<div class='tc-table-of-contents'>
<<toc-selective-expandable '[tag[GettingStarted]!tag[$:/Note]]'>>
</div>
result in this:
Filter error: Syntax error in filter expression
and how do I get it to work? (Make a TOC of all tiddlers that
have the tag GettingStarted but not the tag $:/Note)
p.s. I realize the new CSS is tc-toc. I am using a stylesheet
where I have changed the old tc-table-of-contents to suit my
tastes here.
