For microblogs, as only administrators can add topics, we've found it difficult to field requests from our employees for new topics. It would be great to have a "Request topic" button or something similar near the field, so they can put in a request when they find a topic they need.

This could also be solved by extending topic creation permission, so they could add their own topics as needed (https://linchpin.canny.io/microblog/p/topic-creation-permission).
