   > The rendering performance is also not very great while the "View Samples" tab is open. Sorting that table and resizing the panes are almost unbearably slow. Even adding/removing a metric also becomes slow.
   
   Oh that's what that was. I hit this yesterday and wondered why everything became so sluggish all of a sudden.
   
   > @ktmud Shall we open an issue for performance improvements?
   
   Yeah, I think this is pretty important to fix, as the new layout will probably result in increased use of the Samples tab.
