The ImportTiddlerPlugin filter uses the TiddlyWiki 'paramifiers'
syntax, including any combination of:
space-separated tiddler titles
tag:[[tagValue]]
story:[[StoryTiddler]]
and, I've just updated both
http://www.TiddlyTools.com/#ImportTiddlersPlugin (v4.1.0)
http://www.TiddlyTools.com/#MatchTagsPlugin (v1.8.0)
so that the 'tag:...' paramifier can also accept a boolean expression:
tag:[[tag expression]]
As a result, you should now be able to enter the following filter
value:
tag:[[Project && Starred && !Completed && !PossiblyNever]]
enjoy,
