(un)Collapse everything to a certain depth - any chance it's coming?

Nobody likes Word. Even fewer people than nobody like Word’s outline mode. BUT… man I wish someone would give me a tool in an outliner that emulates the ‘Show Level’ feature from Word. I just want to be able to see, for example, only levels 1 and 2 and have everything else collapsed. Yes, I’m sure I can write a hacky script/macro and couple it with some keyboard shortcuts blah blah blah. But is there any chance this could just be a native feature, with a nice button/pulldown/something in the menu bar?
