Auto theme changes

I absolutely LOVE my ability to just select any new wallpaper and the entire look and feel of my phone completely changes! (I adore the novelty) I would love to expand on this by making it so that I could have different modes for my phone.

So at set times or with the sun or even location; the favorite apps, the names of those apps and the wallpaper/whole theme could change! This would be so much cooler than grey scale at night and you could change how your phone guides what actions you take.

For example at school/work a browser is a portal to knowledge and at home it can be just another distraction on your home screen. And maybe at school/work you want a professional(utilitarian, not weird) look/feeling phone and at home a cute/fun/relaxing one; and even another dark mode for bed time!

Currently I have an entire separate phone (an old one) for bed time with only Spotify (named “sleepy listen “) and a browser (named “late night look up!”) favorited so when I habitually pick up my phone i’m only presented with reminders to sleep and if I must use these apps to use them for their intended purposes, and the wallpaper is stars so it's dark and pretty. It would be so cool if my phone just turned into that mode when it was supposed to!!

P.S. it’d be nice if I could choose a color for the theme instead of relying on auto (which is almost perfect), or the limited other options.
