I think it is ok to print the message each time you toggle it on. That should not happen very often. Just don't show it every time you save a file.

@TrevCraw @turkeylurkey I agree with Paul that it makes sense to show the warning each time we toggle feature generation on. It will not be shown each time feature generation runs (only when toggled on) and on startup if generateFeatures=true.

+1 to show the warning every time feature generation is turned on.
