i've barely done anything, i moved the menu and titlebars up to the top bar (the menu bar sits within the hamburger menu beside the app name) via kde widgets to make it cleaner, changed the sidebar layout by right clicking on one of the items, removed the album artist dividers, reduced the number of columns in the tracklist, enabled the moodbar, and changed the background image to show album art, upped the blur significantly, and turned off the option to not crop it. everything else is just QT settings
