One of the design considerations was "How to relieve the support requests on the maintainers". This is because most support requests in the forum here (but definitely not all) have to do with the application itself (how do I do this?) vs problems with the container (why won't this install?)
Since they're all venues of support, they're all consolidated within the same dropdown, unless there is only a single option available. The order is ReadMe, Project, Discord, Support Thread. On the info screen there's also another option available (Registry).
Or put another way, one of the historical "complaints" about CA through the various UI's (this is the 3rd major UI for CA) is "too many buttons". This version should make it simpler. And IMO it's simple enough to use that all of the help text has been removed.
