Pretty neat huh.
I like the new interface considering the fact that it is better space out than the original one. But I think not many people will like if they had did their branding using wall paper. Now with the new design from twitter, my background is totally block and not be able to see my background.
This is bad news for most people. Just hope that Twitter will fix this one up.
All in all, this is a nice move from Twitter. Keep it up!
