Ok, I can't install this as I don't have either of the 2 devices it runs, but I'd like to chime in with what i'd like to see (though it may already be in the app).
I'd like to have images open IN the app. For example, when someone posts an image on a twitpic post on twitter, it should embed itself in the app. I hate these apps that make you go to the full site to see pics. (Twibble does this, dabr puts the picture right there for you).
Cheers!:)
