After releasing numerous bug fixes and redesigning the interface, WordPress iOS developers are about to add some extra life to the bare bones app.
The most important to-do in the 2.8 road map is Localization. WordPress for iOS will now become much more accessible for many users. 2.8 will also introduce a Stats view (finally!), a Quick Photo button, as well as a few more nifty improvements. (WordPress for iOS)
One suggestion that has yet to be widely discussed would be for the iOS app to embrace post layouts for Tumbl themes using status, quotes, asides, links, etc., similar to what Express App does (minus the hacking or WooThemes requirement).
For those of you who enjoy blogging on the go, what extra features would you like to see integrated within the WordPress app?
