I have gotten used to the new desktop app and I have started to like it, but I'm puzzled as to why there are so many design inconsistencies between the mobile app and the desktop app. Did the developers not talk to each other?

For instance - my contacts are completely different on my phone than my desktop. If I'm at my desk and the phone rings, it will show up as Person A on the desk caller Id and Person B on my mobile caller id. Seems like they would both be accessing the same contact list. Is the contact list stored on each device not on the cloud?

Also, on the mobile app, I love the ability to filter to view unread/unheard messages. Can't do that on the desktop app.
