RefTagger turns Bible references into links to the verse on Bible.logos.com and adds tooltips with the text of the verse.
Thank goodness. Wonderful plugin, also liked ebible and wp-bible, but it was pulling hair trying to support desired translations, or get popups just right. Saved a big headache and the rest of the days worth of stress - it's really hard to find good Bible plugins! What's more, you can style your own but don't think will get into that today - very nice to have an icebreaker - and links for users with Logos Bible Software, all good stuff.
I love the functionality of Reftagger, but I uninstalled it because it was negatively impacting my page load speed.
Have been using this for a number of years. Doesn't seem to be any need for updates. Few plugins work as simply and as elegantly as this. One of my favorites.
