This filter determines which tiddlers will be saved to local storage. By default, it contains `[is[tiddler]]` meaning that it will attempt to save all tiddlers. Other useful values include `[prefix[$:/state/]]` to just save state tiddlers, thus preserving selected tabs, and the open/closed status of table of contents entries.
