Suggestions to improve code editor

[RodionGork]

Özgür proposes some improvements to code editor:

As a user I want to

1. save a file.
2. paste the content of the file to the editor.
3. save multiple files and give them name.
4. see a view of my saved files next to the editor.
5. choose the file and load its content to the editor.
6. give directory structure to the files I saved.
