How do I close a g-code file in Gmocapy?

I'm gonna revive this thread as I'm running into the exact same issue as Ikavan describes.

My g-code files are stored on a Samba and when I open a file from the share in LinuxCNC (Probe Basic in my case) it gets locked.

If it would be possible to add a configuration flag in the INI file or somewhere else that makes LinuxCNC load the file to RAM and then close it to prevent locking I'd pay 200$ without hesitation.

Next step would be to add "Reload" button in the GUI to reload the currently open file. The would save a lot of time during the iterative process of testing new g-code programs.
