I love this plugin. It is just what WordPress needs. When I build sites, I often build them locally with MAMP, then move the site to it's new host home and update the URL references to the new .com.
The problem is, when I use this method after having configured this plugin, I lose my text widgets. They don't drop to "recently used" widgets, they just go away. And only text widgets.
I have tried deactivating the plugin, then updating the database, then reactivating the plugin, and on reactivation, it drops the text widgets immediately.
I thought I'd bring this to your attention, Lately, what I've been doing is just not using the plugin until after I setup the site on it's home, but that's easier said than done sometimes.
