When closing a sequence you are presented with a dialog box titled,
"Sequence Changed Confirmation" and dialog that states, "Sequence changes will be lost. Do you wish to continue?" Yes No
If I wanted to save and clicked Yes, then all is good. If I did not want to save and clicked No, then all is good.
If I wanted to save, but accidentally hit Yes, then my changes are lost. If I hit No, then I am taken back to the open sequence and I can try again.

How about a line that states, "Sequence has changed, do you wish to save it before closing?" Yes No
If Yes, then xLights auto saves. If No, then a new dialog pops up which asks, "Are you sure you want to close the sequence without saving changes?" Yes No
If Yes, then xLights closes the sequence. If No, then you are returned to the original question.
