Clarity for personal use license

I had an issue today because I mistakenly removed the m30 from the end gcode section for individual file structure as I believed it was tool change end not file end.
I think a more detailed tool tip or a field header change would help prevent this for others.

Here is the current tooltip for ending code sequence. M30 plays a starring role, so I'm not sure how to write it any clearer.

            "To combine operations generated individually, the ending sequence "
            "(which should only appear once) must be found. This entry is the "
            "list of G-codes that start this ending sequence. For example, M30 "
            "(end program) would normally be here, but it may not be the first "
            "G-code of the ending sequence. M5 (spindle stop), M9 (coolant "
            "stop) and G28/G30 (move home) are also candidates, but you should "
            "look at the code from your post processor to determine what "
            "will work in your case. Any one of the G-codes you enter here "
            "will mark the start of ending sequence."
