Remember the open tiddlers tab is a dragable list, you can change the order with drag. Also there are settings that alter where tiddlers are opened. So by sorting the actual story river it will quickly have its order disrupted.
Depending on why you want this, perhaps consider an additional sidebar tab that lists open story tiddlers in another order, but does not changed the list. Perhaps include a button to save the order when wanted.
Problem is when I try to write it to the $:/StoryList field, it only writes the first tiddler $:/AdvancedSearch. This is because enlist creates a list.
So I need a way to convert the output of enlist back to a Title List.
