Please Add: Tier row in post overview in Wordpress

it would be super helpful to have a row showing the tier of a post in the post overview page.
to sort and bulk edit posts and tiers.

The simplest way would be if the tiers are also represented as a post category?



That may be a good idea yes. You mean in the post listings page in post admin, in the post rows right. But ‘Post category’ as in?

like this

and that additional that you can set tier_xy belongs to cat_a or cat_a & cat_b

Yes that may be a good idea. There’s an upcoming premium plugin ‘Patron content manager’ from Codebard which addresses such advanced use cases. That may already handle this.
