I tried so hard to get used to not having so many buttons visible... But I simply couldn't. It also turned out that I never liked CoolLine and other similar Cooldown addons - so I made a simple display with Raven that displays my cooldowns in an easy to read way.
Most of it is ElvUI - except for the Focus Bar (Serenity), (de)buff bars and cooldowns (Raven), combat text (MSBT - outgoing scrolls up on the right, incoming down on the left), and raid frames (Grid).
