Great mod!

Thanks, I will look into it!

Note on the second request: If you made changes and close the editor accidentally, you can do Undo (Ctrl+z) after opening again to get the state before closing. (The "Edit" button on the computer pastes the code into the editor, which is tracked as an edit operation in the editor).
Note this is only working until you quit the game (undo ops are not stored in the save file).

Request: Could you please make the ESC key cancel and close the window? This is a feature I've wanted sooo many times.

Second Request: Only if changes have been made, when you cancel (or hit ESC with the above request) could a "Changes have been made, you will lose any changes. Are you sure you wish to cancel?" kind of message pop up (could have an option to disable this popup)? There have been a number of times that I've walked away from the PC for five minutes, come back and gone "did I make any changes?" before closing the window, only to find out I had changed something and I have had to redo it.

Thank you.
