Whenever I have the ruler visible in an editor, and I click on a document in the binder, even if the cursor is at the first line of that editor, the ruler overlaps that first line a bit. It’s a minor irritation usually, but gets more irritating when I’m reviewing a lot of small documents, and keep having to scroll the editor as I select the next document (or use the history or navigation buttons).
I don’t have typewriter scrolling on, so that’s not a factor.
