How does the performance of the "contains" operator compare?
You could use
{{{ [tag[$:/tags/Macro]contains[myidentifier]get[separator]] }}}
where "separator" and "[[My Macro Tiddler]]" are both in the list field of
the global macro tiddler.
Then when the user changes the name of the tiddler, assuming they select
"Update
*Tiddler X* to *Tiddler Y* in the *tags* and *list* fields of other
tiddlers" then the macro tiddler will be automatically updated to allow the
name to be found.
Thanks!
