Did you ever want to add some custom columns to the posts overview page? 
This plugin gives you the possibility to add meta fields, taxonomies, or ACF fields there. 
Just add any number of columns you want and enjoy seeing them right from the posts overview pages.

Posts Columns Manager

This plugins has really helped me and my team to save a LOT of time... 

I use it in combination with ACF in order to display relevant information about my posts or organize them without the need of getting into them...

This might not seems like a big deal if you have just a few posts... but with a large number of them you will really appreciate it.

Thanks to the creator for such artwork :)

Excellent!!!
