Skin looks good when:
— Action Bar disabled in Poweramp settings.
or
— Action Bar and Bottom Action Bar for Equ./Folders/Lib. screens enabled. But Bottom Action Bar for player screen must be disabled.

After installation open skins from Play Market and apply skin.

Skins for Poweramp don't work on most devices from Huawei running Android 6.
