Thanks Ashley! One more I found: bookmark functionality in the PL/SQL editor is not present. However, it's still in the documentation, so I assume (and hope!) this feature was not removed. I tried right-clicking on a line number but the "Toggle Bookmark" option is not there. I also tried clicking the Navigate menu, but it's not there either.
