Almost exactly this. Everything in single row folders at the top of the screen in categories that make sense to me with the most important ones in the dock for easy access. On the next page I have a row of apps I use daily under the folders. The only exception to this is when we’re doing something like going to Disney or flying. I will pull those apps from their folders and put them on the Home Screen since I’m using them all day for days at a time. Now that we have the ability for widgets on the lock screen I’ll put them there and it won’t bug me having them out and about.

My contacts are also hyper organized with full names, nicknames, birthdays, who they are to me or my family, all numbers associated with them and work and home addresses as well. I have all doctors, insurance, customer service lines and numbers for frequented stores and restaurants etc. I get teased about all this but if they need info guess who they ask?
Both DDs do the customized widget thing but DS and DH’s phones are utter chaos. Who keeps their messaging or settings app in the middle of a bunch of gaming apps on page two? Those two. It’s a little surprising with DS because he’s very much like me when it comes to organizing our things. Give us storage containers and we’re happy campers.
