I realised most apps that aren’t on the home screen I just tend to search for by name anyway. So I removed most things from the second screen - but I do have some personally set up category folders (travel, car, camera etc) and the app library isn’t great at combining them well enough to rely on that yet. And honestly I’m not sure the value of the app library anyway - if you don’t use the apps on a second/third screen very often, just don’t swipe over. Search can be done by swiping down anywhere anyway.
I do still keep folders in my dock and homescreen - anything I want to notice a notification that I don’t have ‘pop up’ - so eg any messaging apps I have in a social folder.
Can’t wait for the carrot weather widget - current one is slow to update and doesn’t give me much info. But that’ll be fixed soon enough hopefully.
