There are so many awesome ideas and especially these: Movable UI and ANet developed DPS meter! Moving our own UI will allow you to rearrange it to your liking, to be more practical to your play style and will most definitely improve your over all dps/game play. If you are wondering how can it improve your dps, well the most simple answer is that you are able to see cool downs of your skills faster instead of constantly looking down - allowing you to click your skills sooner. For me it is important due to having an ultra wide monitor, 3840x1600. Yes, I am aware that I can change the UI scaling but I do not want to have a crowded screen. DPS meter will allow players to change rotations to improve their dps and game play in general. :)
