Ultimate Metabox Tabs allows for keeping your post/page and ACF options user friendly for your client with the use of tabs.
Q. The metabox tabs are buggy with certain plugins, either not appearing or having weird behaviour. Why?
A. As of now, on post types at least, Metabox tabs inserts itself just before the content, and pushes itself up via the CSS, this means things that attempt to hide the content may interfere. This can be averted by going to the "Patches" menu and applying the Edit Advanced Forms patch.
Q. Why have you allowed disabling and enabling ACF options and the hide content patch?
A. In the case where I stop supporting this plugin and they break ACF after an update, you can now toggle them off.
Q. How do I make the content only available on a certain tab?
A. Type "+the_content" without the quotations. This is a special custom function. You can now also use the select box to just select it.
Q. Custom Functions? What if I want to write my own?
A. Check out umt_add_custom_command() in api.php (root folder of the plugin)
Q. I want to write a custom metabox tab settings page. How?
A. Check out api.php and extensions/acf/acf_options_mod.php, If there is more demand for extensions, I'll write more thorough documentation.
