As we continue to evolve with the iPad and other tables becoming more and more daily workhorses we are still lagging with the same expanded iOS app for the iPad. We need an option within the app or a new app that allows the side bar to stay on and a better UI for the iPad App. A replication of the webUI would be totally fine (or the same as the Mac App). Fastmail for example allows a toggle within their iPad app to enable “Desktop Mode”. Providing this option will give some of us power users, using the iPad now and going forward a more intuitive UI.
