Thanks everyone, much appreciated.

Here's my plan for now until I get more of a chance to digest some of these good suggestions:

#1 Keep my wits about me more and try to pay attention to what I'm doing at the moment smile (Ounce of prevention thing....)
#2 Frequent file Save and Save As-1, 2, 3 etc. (incremental saves) as I've been doing in every program and project for years.
#3 Rely on Undo as Plan B
#4 Keep hoping for a "padlock" feature in a future build if it's possible to do.
#5 Keep enjoying RB and BIAB, and of course , pickin' and grinnin'. smile

Thanks all,
