Google’s new beta test program is out and Mimi is now on it. I’m not sure how it works, but I do know that the first step is to join the Mimi Reader Google+ community. Once approved, you should have access to the Mimi Reader beta program.
There is a version up now, but it has very limited changes. It’s basically just a change to the new Google drawer slide out pattern. All you should notice is now the sidebar is smaller.
Request access to the Google+ community here.
Once you have access, I think the beta will appear here.
Of course I’m probably completely misunderstanding something and it’s all broken. Eventually it will work, though.
