This hook allows plugins to add to or remove from the list of tiddlers that are opened when the wiki is first loaded or the home button is clicked.
Hook function parameters:
- list: array of tiddler titles to be opened
- modified array of tiddler titles to be opened
Note that this hook is invoked with the tiddler titles that are generated from the filter in $:/DefaultTiddlers. Any added entries must be tiddler titles, not filter expressions.
