Thanks I appreciate your kind words Some of the ideas I have in mind are   adding information concerning online copies of journal papers lots of journals publish at least a part of their papers online for free  the system should inform the user that at this and that url there is probably a online copy   more or less automatic updating of the db according to the growing use of ref templates in WP articles  extending this to multiple Wikis eg German French etc need multilanguage support but also separate wikilinks according to language etc  extending this to other areas Physics Computer Sciences etc  user management which will become necessary when the DB gets the attention of vandals etc
