Actually, thinking about this you might want to follow the
$:/AdvancedSearch pattern.
Store the output of the filter in a $:/temp/* tiddler, and display those
results in a list for the user.
Then have the button use the $:/temp/* tiddler as the source to
clear/update the JSON tiddler.
Then the displayed list will auto-update as the user changes the filter,
but it is up to them to confirm the new selection into permanent storage.
Best,
