A similar capability is exposed in Jira and I saw someone online requesting the functionality.
What it does
Allows you to easily include information about the Page inline in your Confluence Pages.
How I built it
Using the atlas-connect tool to create an initial Nodejs app. Functionality was then added using the Confluence Connect API.
Challenges I ran into
Really nothing major as the Confluence API was very easy to work with.
Accomplishments that I'm proud of
How quickly I was able to go from having an idea to a working app.
What I learned
atlas-connect and the Confluence Connect API have made creating an app super easy.
What's next for Smart Values for Confluence
Adding more template tags and solving more problems for customers
