+jQuery breaks on dashboard pages that utilize CFM
+It does not appear to use real custom fields. One advantage of using most Custom Fields plugins is that it actually tucks the custom field data in your database permanently. So even if you deactivate that plugin your CF data remains intact. CFM puts that data somewhere else (I don't know where) and the data does not go into standard Custom Fields making it very difficult to use in your templates and useless if you uninstall CFM
+It does not appear to be supported anymore by the developer, but the developer has a fantastic premium plugin called Advanced Custom Fields which will pick up where CFM left off and then some in a more elegant way (but the catch is that to get ACF up to speed you need to pay for the add-ons...Still, I think it's worth it).
Sorry, I had to get that off my chest. I'm in the process of going through post after post and changing custom fields data because I made the mistake of using this plugin and found shortcomings with it later.
NOT REAL CUSTOM FIELDS!!
