I found a little mistake in wikipedia links of sample data after installation also it isn't bug but a littrebit annoying. You take a 'http://' prefix into the fields "wikipedia" in "jos_joodb_sample" table in database and my joomla is replaceing that to a link but your's "Single entry view template" is into an "a" tag href's attribute.. also it is not work.
but is a great job! Let's more! :)
