We are evaluating knowledge tools, so created a couple new trial sites, and are not able (per screenshot) to add apps in the dropdown menu "find new apps", despite being admins, trying multiple apps, request/approve, etc.

curiously, I AM able to get Gliffy app to show up in side bar by using the associated template, but I have not found a template for every app, and the UX/support has not made a great first impression...
