The web client is a horrible experience on the Mac. The design decisions of the group that put it together are horrible. Why in the world did they think that sticking the app to the corner of my screen is okay? Why does it follow me across every workspace? Why do they insist on interacting with the application in a different way than every other application on my machine?

If you want to make a webapp, fine, make a webapp and leave it in my browser like every other webapp. If you want to make a native client, make a native client. Don't do this half-assed crap that does nothing well.
