As you may be aware, the Poweramp developer has been working hard on an updated material design user interface for Poweramp v3 which required a full ground-up rebuild of the code and is taking some time to get to a beta-test stage. See the forum thread for more details and to discuss.
Hi, I picked up a Galaxy S8 today and because of its taller screen and wider aspect ratio, Poweramp doesn't take up the entire screen which is very frustrating. Please consider implementing this into the next update. Thanks
