I have added custom term meta to my taxonomies through ACF and it would be nice to be able to see the values I have assigned to each CPT in the post editor queue for my CPTs. Right now, I have to open each one to view the value I have assigned, then back out to assign numeric values to other posts and the problem will only compound as the items in my CPT grow. For a link to what I’m talking about here, it’s something along these lines:

Currently, I have a field group called ‘sort_order’ and I am assigning each CPT w/ a numeric value tied to the taxonomy so I can better control how the terms sort when I output a menu of terms on the front end, as I want to prioritize certain terms over others vs. their default or the orderby options WP natively allows.
You’ve already linked to some instructions on adding custom columns to a CPT. Adding custom columns to a the taxonomy list works the same way, here’s a post for it http://wordpress.stackexchange.com/questions/77658/custom-columns-for-taxonomy-list-table.
