As with Discover, let users open multiple items in a tier report and keep the data on screen, instead of reloading the entire report and collapsing one branch to open another.
Was just talking about exact same idea this morning. It's not just a redraw issue but even being able to see two or more branches at same time for context and comparison. For graphing it could still just show one branch i.e. let us click a branch to show.
