So I’ve use this quarantine time to rebuild my while UI using mainly button-card, decluttering-card, card-mod, swiper-card, some picture-elements and a hell lot of yaml (almost 1000 lines of yaml for the button-card templates) 
I inspired myself with @Mattias_Persson’s UI (and also used the circle from his code 
)
The media-players are not using mini-media-player but button-card.
The goal was simple, less stuff, more info at a glance in one page and popups on hold_action for most of the cards (sensors would display a graph with mini-graph-card, lights would present a clean popup with color, brightness, effect based on what they support, etc…). And multimedia management of course 
It’s a bit out of topic, but it gives you some examples of what you can achieve with button-card by tweaking it the way you want.
I’ll share some of my templates later
