A specific subscription banner is not on the roadmap for the next drop and is not a priority at this time.
We are currently working on features that will enable our customers to extend the capabilities of their content through a set of extensibility APIs. This is a fairly large effort and one that will evolve over time. We plan to release the initial set in Q1, and follow up with additional APIS, plus features to extend banner capabilities (e.g. “HTML cards”). I believe that with these APIs and extending content capabilities we’ll provide our customers more options for engaging their end-users.
Agree with Chris and David. It still surprises me on this issue. As Adobe advertises AEM Mobile as the benchmark enterprise solution, there are many items missing that were available for the last 3 years with DPS. It has been made clear that DPS is ending and developing in it is a dead end street. We need these ASAP. Hiding the 'Sign-in" function is a serious problem for users. That, and the ability to make a subscription purchase needs to be upfront in the Browse page
