+You can use the [[search-replace Operator]] in combination with the [[sortsub Operator]] to ignore stop words like "A" and "The" at the beginning of titles when sorting. (Note for example that "A Tale of Two Cities" sorts under "T" rather than "A")

+
+You can also customise the listing so that "A Tale of Two Cities" is listed as "Tale of Two Cities, A" but still links to the correct tiddler.
