I think a few of the web-based features should be added to the app so that they can be used in games that take place in the physical realm with roll20 support. The main thing I'm missing are the options related to hiding or showing characters and handouts from the app when I log in as a game's GM. It forces me to access the web with the mobile browser which in turn generates a different set of usage problems. Also, it would be needed to be able to see, edit and move the map and the tokens on it on the mobile version, in order to be able to usefully use that function while in the same physical space. :)
