Great for the anal-retentive among us

I have to admit, it was really bugging to know that I had all manner of ACF fields that I had replaced, reconfigured, abandoned etc. during the dev process, and when using any theme builder to assign ACF fields to various modules, I was seeing fields that I had long ago abandoned. In one case I went from a custom field in a CPT, to a taxonomy for that CPT, and I used the same name, so that field was still in the database with some values entered for it, and in my theme builder I saw two different field assignment options with the same name ;-( Yes, I could work around that, and it is not bringing my site to a crawl or anything to have the superfluous fields in there. But I was able to use this plugin to easily remove that field, along with a few others I knew I wanted to remove, and even some I had forgotten about. So kudos for giving folks like us a way to clean all this obsolete stuff out of the db.
