I had to Google it.
“Drag the app to the trash bin.”
Remember how hard it is to uninstall stuff on Windows? Especially if you’re doing more than one?
Dragging is cool, but doesn't make the uninstall process better than Windows apparently
On Windows, when you open a photo by clicking it, you can go to the next/prev one using the arrow keys and on macOS you can't do that. So the Windows immigrants get annoyed, naturally.
On Mac, you can simply select a single file anywhere and hitting pace will very quickly show you the contents, hit space again and you are back to the folder. You can use the arrow keys to skim around and the file contents will be quickly displayed. If you first select a bunch of files and then hit space, it will loop though your selection when you use the arrow keys.
It's a very convenient feature to skim through the files in a folder.
