Drag and drop traits anywhere in world building files

At present, once a file is created in the World Building section the traits within are set with all new traits added appearing at the bottom. This is very frustrating if you are trying to keep information in that file alphabetically organised.

The alternative is to either build a field for each letter of the alphabet and then put all the information within as subheadings, or, to just use a file for each piece of information - making the story bible cumbersome.

The solution is to make the traits/fields drag and drop, but on top of that, please create a second button for creating a sub-folder and a third for creating a sub-file.

Options should be create folder, create file, create trait. All three should be drag and drop. (I know the hierarchy crosses over with other suggestions, but I may as well mention it as it applies - consider this suggestion purely about making traits drag and drop).
