We now have a great tutorial that launches with product installation, and can be turned off in the new preferences panel. We also have a great new retina clean timeline, browsable images for every empire, preferences, and bookmarks for the wiki view.We've also cached the summary articles for every empire in the app, along with the top level of maps, so that users can do even more when not connected to the internet.Finally we've added a feedback button in the preferences, so users can chime in and help guide our product to the future.
