For me it’s the Mac Finder. It’s always running so (unless it crashes) there’s no delay in opening a file manager window and, more importantly, it has built in Quicklook and Miller columns. Haven’t managed to find a good-enough implementation of either of those in Linux, so I just work around it.
nothing beats the mac finder, mac touchpad, and mac scaling/ui. other than that, linux does everything windows/mac does, but better. imo. so definitely in agreement here.
It just lets you opt to see the folder size as an attribute in list view the same as you can a file in Windows or Linux. It’s more or less the same info as disk usage analyzer but without the flower and displayed inline which is useful and convenient.
