To change the people who are mobile.
You just need to change it where you can see who's mobile. At least give the mobile screen names a little blue circle. And change it to green when then come online. It's sorta a pain in the ass that you can't fucking see who the fuck is really online and who's not. >.< and add something where you can see and comment on people's life streams. Like I loved that on the old aim. This is bullshit that you can only see their status and not able to comment it. Other than those two issues the app is ...alright.
