Or the ability to drag a rectangle over multiple nodes to enable, similar to clicking and dragging over files in a file explorer, which would remove the ability to scroll through the program by dragging the program tree, but given a program can be scrolled using the scroll bar, I personally would prefer the ability to select multiple noes at once.
I know that the Doosan robots have a multi-select mode for copying and pasting multiple program lines. They also have a Desktop version of their programming interface for making changes and then syncing them over to the robot with one Button.
I don’t mind programming over VNC if I have a desk setup by the robot, but getting rid of that latency with a dedicated desktop App would be nice.
