as seen at the new gutenbook.org site [1]: "A whole heap of enhancements and features... Implemented page searching; Implemented user preferences and preference interface (note that cached index auto-update is currently disabled); Bound key "p" to preferences interface, "Ctrl-p" to page search; Implemented local index caching; Cached index represents local etext presence; Implemented etext auto-save feature; Implemented etext read-local feature." Most definitely appreciate the shouts, too. :)
