[Feature request] Make the bottom-right 'Code' field editable

[paulponcet]

Would it be possible to let the user edit the Code field to push their own ggplot2 chart?

I'm not sure if what I have in mind is the same as @paulponcet is asking for, but my workflow is often that I use esquisse to make the first rough draft of the plot, insert the code into my script, and then go on to customise it with extra options not available through esquisse. If later I want to change something, I edit the code directly.

It would be great if I could reload the customised plot back into esquisse, for example to change the geom and theme.
