Just to add some flavor here - the page select buttons are 3 across because I couldn’t make my finger reliably hit the right button when they were 4 across. You can change which 3 pages are available on those 3 buttons from the web UI right in Home Assistant, that looks like this:
They directly access a specific page, because when I walk up to my HASP I don’t want to cycle through 8 pages to get to where I’m going. The design principle at work here is that interactions should be nearly as quick as interacting with a light switch. I don’t want a zillion options, because for interactions like that I have a zillion options - mobile device, tablets, PCs, etc.
None of this is to say that you can’t just add that behavior yourself, but things are they way they are for that reason. I use these mounted in my wall every day, I have other people in the house who aren’t turbo nerds, and I have worked pretty hard to make these things simple to use daily for normal people once installed.
