The usage of Advanced Custom Fields saves a lot of time for small enhancements. I’ll always prefer to do this directly, without the usage of a plugin. But a lot of projects, small enhancements, extending of functionality can be captured by ACF.
I’ve been using ACF PRO for almost a year now, and it definitely saved me time. The gallery and repeater field are one of the more complex and very usable fields. ACF also support adding custom menu pages, so Site Admins can configure some stuff there too.
Elliot Condon made this plugin and he does a really great job maintaining it!
Thanks Elliot, for this plugin! Check out ACF at their website.
