Can we have the Skip/IUnSkip buttons back, please? It's not a productive step having to select a dropdown. It's more difficult to scan this new page than before. If I am scanning to see if a message is relevant by the time I move my eyes across the huge expanse of white space to the action it is very easy to lose your place and be looking at a different message.
I agree the message screen needed a tidy up but the implementation of filters would have been better.
The original vertical layout was quicker and a better use of screen real estate. Can you please come up with a better solution.
