UX: File Editor - Input not in focus

Small, but annoying usability issue:

As a user/an editor of files…

Having created or selected a file in the file list I expect to be able to immediately type / edit the content, paste the clipboard in.

Currently, you have to first click in the field before you can type.

Clicking CMD+V to paste the contents of the clipboard in

After Opening the File Editor the input field should be in focus.
