Uhh.. you brought philosophy and windows 8/10 into the discussion, on all of which, but the win 8 interface, I'll beg to differ.
But just regarding the new Poweramp UI, I'm okay with the design change (not hating on the previous).
I haven't faced any accidental/miss-swiping. I'm not fond of the text on the black-bars over the album art but I'm not able to relate to the strong allergic reactions on this forum to that text, nor to the hatred over 'material UI' looking horrendous or anything, or even to the flaming on the wave-bar. Only a few users, forum/non-forum, would even be able to classify this UI as 'material'. I think the main screen looks just fine, if not a bit better than the previous UI aesthetically. The blur customisation on the main screen is a fun addition.
The wave-bar helped me to move precisely to the few seconds, to listen to the voice/singing on that very part, fat thumbs used to make precise seeking very hard with the seek-bar. The wave-bar concept is something new to me and it looks good, just hoping the bars themselves get fixed soon to properly relate to the quiet and loud portions of the song.
However eventually an option to toggle buttons/gestures and customizing the text, as well as reducing the width of the wav-bar should be nice.
As of now, I'm just looking forward to
the HiRes functionality getting fixed,
the star rating,
the ability to delete and
Occasional crashing and not opening unless you wipe its data, as soon as possible; followed by the numerous things Max has already put in there, but they don't work yet, but I can wait for those patiently.
