Improve file management UI in graph editor

[AlexBxl]

Overview

There has to be some preset by now, to get good file management explorers 😆
Every app has to implement this crap, and users have to figure out which features are missing for this implementation.
Give me DND, Trashbin, Copy, Directories, Import via drag and all that stuff I'm expecting from professional software

Also I want previews like this in the file manager
