This is one of the features I never miss and don't use on any other DE (like KDE). I just open the app, create the file and save. Maybe it's just habit, but I personally doesn't find it as a needed feature.
> There's no easy way to cut a file/folder (Cmd-x doesn't work)
Just drag it where you want while pressing CMD? I know it's not cut but it prevents a lot of errors I think.
> There's no (?) way to keep everything consistently sorted and aligned
It's called "Clean Up By". Available in right click menu and in the top menu probably. It'll always keep the order you choose.
> Tags are useless and just take up space for nothing.
On the contrary, this is something I love. I can just throw a bunch of files to a folder and tag them about what I'm going to do with them. Colors allow me to mentally sort them with no overhead.
> No "parent folder"...
Two-finger click to folder name on the finder. The path will be revealed as a reverse-ordered stack. Or just press back. It's parent folder 99% of the time.
