I would prefer it if Apple's priority with MacOS was fixing the numerous bugs in Finder that have been present for years, providing auto-sizing of columns (since they've nobbled every third-party app that enabled it in the last 20 years), and enabling system-wide font management that hides the numerous bloody fonts that are of no use and clog-up font menus.
Add to that a means to separate and label bookmarks in drop-downs, and allow white-listing of cookies (Safari), and organise genres in a user-defined order and stop attaching unconnected artwork to playlists (Music).
