As of right now, all I'm thinking of when I launch Action is to see a big "update" message pop up. Since I have no idea of how far you've come, it could be out in two years or within the minute.
It would be awesome if someone from the team could do a short update of what has been done and what is next in the line (maybe keep surprises surprises). That way we would have more knowledge on when to expect it.
It doesn't have to be an entire changelog, just a small mashup of what has been done and what is planned on the Forums, Twitter, Reddit, etc.
