This is such a valuable plugin, countering the particularities of WordPress. Had become anxious since I was planning to change my theme, as to what might happen and the hassle I would have to get into to fix things...
This is one of those "must have" plugins you won't know how much badly you need them till you actually need them.
That's the point of plugins really, isn't? And the most essential ones are the ones which answer to potentially universal needs, responding to the way WordPress works.
Keep this plugin alive!
