One minor bug I've noticed (not limited to the new build) is the "scroll to" location of the left pane on a "Browse user's files" operation.
Expected behavior is that right pane shows dir contents, while left pane, which is typically a very long list of expanded dirs, would scroll to show the current selection
Observed behavior is that right pane shows dir contents, but left pane is scrolled to a portion of the dir list that does not include currently selected dir
Right click on a search result, select "Browse user's files"
View switches to "Browse" tab
Split pane view shows dir hierarchy (Left) and dir contents (Right)
Left pane scrolls to a random portion of the dir list that does not include the currently selected dir
