The replace in BV will be taken care of by not doing it
As for a toggle, the effort/impact for doing this is troublesome when its planned to replace the cause. I know user_none's said this before, but now I can see why he says it
A bit more patience and hopefully a more solid version will be forthcoming after the 5.1 release.
As for the find/replace in BV, I was wondering how to address the very common issues that users have of wanting to only replace certain sections of text. Instead of cluttering up this thread, I'll start a new one requesting Regex suggestions.
