From a person with actual knowledge on whats going on

For everyone who is complaining about updates, shutup. Everything that is on computer as of version 1.3 will be added to mobile. I believe it is coming in one update so its gonna take a while. Having the change the UI and basically handicap the content tends to take a while. Along with the limited hardware thats on a phone, it could be a long while until you people get a major update. So stop whining and just bite the bullet for some time.
