It wont be a full size mode, but we're working on a general layout improvement for the code editor which lead us to a much wider editing area

Hello alexandre.fritsch@abtasty.com Thanks for your request!

The Nautilus team will soon work on a revamp of the code editor that includes moving the variation panel to the top. This way, we will have more space for the code part.

This revamp should be released in a few weeks :)
