Few sugestions for new version

I want to gave here few of my own suggestionos from my own expierence of working with gmoccapy

• Optional warning when feed override is zero during program start. I see many times confused people wondering why machine isn't moving and there is no error or something, the practice is known in another controls like Homag PowerControl
• making gmoccapy version for HD screens, as it becomes more common these days. perhaps it could be done with some .rc file like version for 800x600. It could also fit some extra buttons horizontally (I calculated 13) so we could show them or hide depending on screen proportions
• Fixing situation when I editing the code and someone activates external estop. Now it closes the editor and jumps to locked manual screen and my changes in file are lost. It should allow to save work and allow to go back to safety but not throwing you out of your work
• Maybe adding some basic controls to file editor like copy, cut, paste, delete and rename file. It would prevent the situation when I'm forced to go back to desktop for simple file copy from pendrive. This break the immersion of professional control
• also as we now logging situations in gmoccapy it would be nice to have graphical interface in program to read this entries (probably from settings page). In many professional controls there is a log of actions so the supervisor could diagnose the machine
• one last thing it will be good to have some kind of interface (again maybe in settings page) to quickly make a backup of config and nc files (maybe to choose). It is good practice in machinig to doing it periodicll

I'm open to discussion of my ideas. 
Also some of them I perhaps could incorporate myself as I already did some but versions going up quick and sad part is I still don't find time to understand github... sorry Mayby some could also help a bit
