I'm also a fan of the RW Tool and of Mike - who is great at replying to questions and being downright bloody helpful.
It's a total Swiss Army knife. It has heaps of functions.
From basic swapping stock to making scenarios (my work space) and route stuff "easy". but yes, the advice is sound, there are some awfully powerful functions, so you have to choose carefully what you use....
Ensure you backup before you explore it.....maybe common sense, but worth saying!!
or as the Romans learned the hard way....pillage THEN burn....
