I know, that might sound rude (it isn’t meant that way!), but you need to get a little more familiar with how HA works.
What you’re asking for is a new dashboard. These you can setup under Setttings. 
How to move forward with this dashboard is entirely your choice - generated like the Overview dashboard you already have, or you take control and do it yourself for this dashboard.
On this new dashboard you can setup cards as you like. Small, big, with or without sliders and so on. As you already got the most important links for your specific need, I’d recommend to take a look here, on how to work with HA.
