Pleasantly surprised by this app. While apps don't give you a lot of latitude when it comes to your Office files, the interaction and design of this app will let users add a level of functionality previously almost impossible to replicate. So far this is hands down the BEST app for Office I've ever used. Only received a 4 of 5 stars as it's version 1 and there are a few, very minor bugs. Trust me, I'm a hard sell, and I'm very sold on this app. Very well done!
