For what I understand of your comment, when you want to show where is a searched bookmark item in the tree, simply click on the search result you want to look for, or right click on it and click on "Show bookmark" in the context menu, and the bookmark pane will smoothly scroll to where your bookmark is, highlighting it.
Or let me know if I am misunderstanding your comment.
Thank you, aaFn.
