When in editor and hyperlinking a word in a post, it would be a great idea to write a word/keys and dynamically search for matching topics. Because I’m finding myself linking references to other topics.
I saw a similar feature on some wordpress plugins, to easily put anchors and relate content.
You can kind of do something similar when composing by opening the header search, typing your query, using the down arrow ↓ to select the topic you want, and then hitting a to insert the link into the composer (totally recognize that it’s a power-user feature, and something in the hyperlink modal would be much more discoverable).
