Marketplace apps for end user / organizations?

I'm interested in adding more information about our end users and organizations and improving the sync with our CRM, and availability of that data in more contexts. For example, it's very helpful to have the Salesforce info in the app drawer on ticket screens - it would be helpful if that info was present on the end user and organization screens as well. Even with the Salesforce integration enabled, on those pages it's "There are no apps visible from this location". Totally makes sense with that specific app, but are there any apps that are visible from end user/organization screens?
