I have to say that the new GUI is not very userfriendly. (It is fine to follow design trends as long as it doesn't spoil the user experience - in this case it disturbs the user experience). The GUI now looks more like a early alpha build, than something you would expect from a really pro utility. As a media professional I disagree with your design choice, it would be NICE if you at least implemented a function where users could choose to revert to the original GUI if they wish to.
Thanks,
