+
+The Issue.Ref was added by Add possibility to record branch or tag information in an issue (#780)
+After 8 years, this "branch selector" does nothing more than saving the branch/tag name into database and displays it.
+
+There are still users using it:
+* @didim99: it is a really useful feature to specify a branch in which issue found.
+
+Still needs to figure out:
+* Could the "recording branch/tag name" be replaced by other approaches?
+	* Write the branch name in the issue title/body then it will still be displayed, eg: `[bug] (fix/ui-broken-bug) there is a bug ....`
+* Is "GitHub-like development sidebar (`#31899`)" good enough (or better) for your usage?
