The real tiddler supersedes the original shadow tiddler that was loaded from a plugin. However, the original tiddler is still "lurking in the shadows", ready to be re-applied if you delete the modified tiddler, so that you aren't left with a hole in the system. The filter terminology for referring to overridden shadows *is* somewhat confusing, linguistically. Perhaps it might better be interpreted as meaning "[is[shadowed]]". Also, note the difference between "overwritten" and "overridden"... the first term implies a direct replacement, while the second term implies a prioritization of use. I hope this explanation doesn't confuse things even more... -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
