FYI, this topic came up before (several times), and then:
It’s been part of the user feedbacks from day one, BUT it’s also quite understandable that C3D now has a very large user base to manage, and, how do I put this gently, some of the users want to use their machine like it’s an iDevice, so the workflow needs to be foolproof.
Considering Rob’s answer above (again, perfectly understandable), if this is a problem for you, you may want to consider using another G-code sender to use a specific workflow that will best suit your habits.
