I find a gear or cog more conceptually engaging than the "hamburger". Open it up and look at how it works inside, maybe tinker with it. The three lines have no distinct relation to me that isn't artificial, as least the floppy icon is tied to something that might have a historic meaning. These days I'd probably have a checkmark and a broken checkmark to denote 'checked in' and 'not checked in'. Crucially it would probably need to be two checkmarks when fully checked in, and a single big checkmark in back with a smaller obviously broken one in front to denote an older version exists.
