I decided this year to go minimalist on my phone and iPad, and only have two screens on both, mostly just widgets now. All apps have been moved to the library and I mostly just open stuff by pulling down and using search (I never thought I’d be one of these people, but it’s so much easier than scrolling to the app like a mere mortal 
).
I was going to be brutal and delete some apps that are nice but that I rarely use, particularly after seeing posts on here, and I did delete a couple, but then I felt uncomfortable not having them to hand so I put them back. Since they’re in the library they’re not bothering anybody and I don’t see the point in stripping my iPhone and iPad down further.
I haven’t embraced this on the Mac, and it’s for a really annoying reason: I wish there was a way to make the notifications/widget bit stay on screen permanently. I have a wide screen monitor; I can afford the sacrificed real estate and it would be so useful just having that bar with my calendar view, task list, latest notifications etc always visible. I hate having to go find it and thus rarely use it. In fact I pretty much only use it when I’ve missed the alert for a new Slack message and bring up notifications to see if it’s something important or something to ignore for now, and probably 60% of the time I don’t even do that, it’s often easier to just look at my phone notification to see if I need to respond immediately. (My Slack often has a lot of unread messages so I find notifications easier for checking if I actually need to open Slack and do something or if it can wait.)
