make monaco optional in editor

I found when install the editor, it tries to install the monaco editor which has the size of 10 MB.

But I'm Trying to make this as a plugging for the tiddlywiki, which is very sensitive to the size. (It's a single file HTML wiki, portable with its small size)

I hope I can replace it with a simple textarea, or inject a codemirror to it.

And from the playground, I notice that monaco is within a popup, which might be outside of the flow editor, so it is truely optional?
