In web development, I get used to place css/js files under separate folders (css folder, js folder ..etc).
What I am experiencing in WordPress is that I cannot access these folders in WordPress Admin Editor Page, the editor only displays the files under the main theme folder, not the nested folders.
Is there an option to enable showing nested folders? is there a plugin to accomplish that? If not, then what is the best practice to follow for placing files and folders under WordPress folder?
