Is there a way to freeze Bookmarks?

What happens is that I create bookmarks, I go back to them and find they’re gone due to some action that obliterated an entire section that happened to contain the bookmark.

Maybe this is a matter of being more organized, such as putting bookmarks in a special area, but that kinda defeats the purpose, as we want the freedom to assign bookmark status anywhere.

Not sure what you mean by “freezing” in this case. Did you want to create a copy of it so that it doesn’t get wiped out?
