I found myself wanting to view/change the Jira configuration for my project, and was frustrated that there wasn't a link to do so from the Jira/Jira Issues nav item in the left sidebar.
Users whose Gitlab instance uses Group or Instance-level Jira configuration may want to change the configuration for an individual project, but have to navigate to a different nav item Settings > Integrations > Jira to do so. This might be confusing to users who are unfamiliar with the Integrations section.
