I've been having a difficult time keeping track of related issues. Sometimes issues get linked by the team, but other times people only reference another issue in the comments. This effectively means that the "link" is one-sided.
If you visit the page of the issue that was mentioned, you don't see any indication that the issue has been mentioned somewhere else. Here's an example of how this feature is implemented in GitHub.

I'd like to see this feature in Jira. Anyone know of a marketplace app that delivers this functionality?
I'm also going to look into the capabilities of Jira Automation to see if I can make this feature myself.
