For future WordPress versions, I'd like to suggest that there's a folder/directory called "wp-general" where the root files will be stored.
The reason for this is, when working in an FTP, it's annoying to have all those files (that hardly anyone ever touches) just laying around taking up space. With a "wp-general" folder, it will create better organization and users will only see 4 main folders/directories: "wp-content", "wp-admin", "wp-includes", and "wp-general".
I hope this will be taken into consideration when developing the next version. Thanks.
