I also joined the forum to add my vote to bring this back. Poweramp was the first store app I ever purchased when I moved to Android many years ago. Solid, innovative,and well maintained. Using the swipe up/down to change albums without looking is just great touch design. I have been trying to adjust to v3 since it came out and, like others, assumed there was some combination of settings I hadn't discovered to keep that function.
Sorry, I am reverting back to v2 until this is restored as some option.
