The Objects List - Highlighting objects and keeping it open when removing a single object

Two things to make the objects list really shine. (This is regarding the objects list at the top of the chart.)

1) When you hover over each object, the object should also be highlighted in the chart area (so you know which one it is!)

2) When you click the 'X' to remove an object, the object list should not close... it should remain open so you can review/close more objects if you wish. The objects list menu should only close when you hover your mouse away (just like most other menus).
