Just between us: you will come to a point eventually, where you will hate the possibilties offered - because you can’t decide what you really want! 
And after that, there is no way out. From that point on, you’re trapped inside Home Assistant and will never, ever get oout again!
Welcome to the loony bin! 
EDIT: There is another project, that was kind of a starting point for Mushroom, UI-Lovelace-Minimalist! There you can configure even more, compared to Mushroom, but it has a steep learning curve and is, imho, not for beginners. You need to know what you’re doing with YAMl. But if you do, with Minimalist you can practically design everything in a HA dashboard…
