I'm using javascript. For searching the objects during the test we use webpage.FindChildByXpath(xPath). In the Object Tree I can properly see parent/child relationships.
Like in my previous reply, I did disable Extended Search but didn't see any differences.
What kind of issues for the web app do you expect? Everything behaves as it should, both slow and fast runs of the test get a green log. Only difference is (from what I can tell) that the fast run doesn't seem to need to search for the objects as it already knows where they are and where to click/type test, whereas the slow run needs to search for them.
