Ultimately remoting into the BBB still means learning two operating systems when 99.9% of my work is done under Windows.
To drag a drop a file onto the desktop on the Debian BBB MachineKit port involves dragging it to the desktop folder and then using the ever present and needed text editor to edit the shortcut to make it work properly with the correct icon. In windows you drag it onto the desktop. Period. If you want to change parameters right click and change stuff in a dialog. No command line needed. So if LinuxCNC is to be used in windows getting rid of the "Linux Guru required" option is a major feature.
