How to make the recommanded topics collection

In my community’s traditions, it’s popular that the moderators mark the topic with recommended.
I think it’s a good method for increasing the visibility of high quality topic, community interactions and motivations.
Pinning the topic on top is another method to make the similar effects I’m using.
The difference is pinning is better for visibility but lack for community interactions and permnant recordings. It’s an honor to write a topic which is pinned or recommanded, but the pinning is not officially memorable which people want.
This is why I usually pin the official notifications only.
Anyway thanks for your advice.

Can you explain the meaning of “mockup” for me? I’m not a English native speaker or a experienced discourse user.

I think this is what I want and very appreciated.
I didn’t found the tag management page before. Going to check it now.
