Broken Files Tray

Right now Files Tray uses a questionable way of storing files and folders and it doesn't work as it was intended to.

A few bugs that comes out of it are:

• Dragging and dropping files from NN to browser doesn't work
• We can't copy files with cmd+c
• We can't rename files
• We can't right click files
• Right now the X button to remove the item from NN isn't working
• It duplicates files when sometimes

While we surely can implement and fix all of those issues by hand, I feel there's some better way of presenting a file. I feel like there's some way to inherit all the files options from finder.
