I imagine this is a known issue (is there a publicly-accessible list of these somewhere so I don't have to report things you already know about?), but in case it has been overlooked or forgotten…

After collapsing the styles portion of the utility drawer (either by double-clicking the divider or dragging it down to the bottom), when the style pane is re-opened, the contents of the view have been shifted up and the top portion of them is cut off. At this point, dragging the divider will not cause the contents to "snap back into place"; the only way to restore the view properly is to close and reopen the document.

I seem to remember reporting this at least a couple of years ago. It's not a showstopper or anything, but I'm kind of surprised to see it still hasn't been addressed. One gets the impression that OmniOutliner is in "maintenance mode", with someone putting out fires in their spare time and nobody really focused on making it better.
