Rollbar reports currently only list Environment, Language, Framework and Links and not the actual Project in which the error occured.
Would be nice to include the project title in the output.
To accomplish this, you'd have to get the project_id from the JSON report and perform a GET on the Rollbar API: https://explorer.docs.rollbar.com/#operation/get-a-project
Additionally this would require a setting to be added to the plugin to store the X-Rollbar-Access-Token for the account.
