The power of WordPress is amazing, but I don't understand how two very basic concepts aren't part of the media library.
First, how is there no option to replace an uploaded file? Seriously? I either have to delete my file from the library and upload the new version, or replace it through FTP access. This is a very basic necessity for website management.
Secondly, there really needs to be a way to organize media. I personally prefer the idea of folders. I like it looking uncluttered. With this, there should also be the ability to customize the slug, just like with pages.
Categories or tags would work well, too. And, please, give me the ability to have images displayed how I prefer. Right now, it's newest to oldest. Can't I have them display alphabetically? Or even group them by their categories or tags?
Plugins options are nice, but these seem like they should be part of the core experience of WordPress.
