Well done @jimbobrjames!
I’ll give you a little tip that I use a lot to simplify this configuration. With the new syntax, you can store repeated values in variables to reuse them in other places.
c::set('meta-tags.default', function(Page $page, Site $site) {
$title = $page->isHomePage()
? $site->seotitle()
: $page->seotitle().' | '.$site->seotitle();
return [
'title' => $title,
// ...
Then you can just use $title
in the other places you repeated that bit of code.
