It divided for two sections: Vista items and Vista item properties
Vista items - allows you to turn on/off visibility of the objects on the view. This is dynamic part of the window and shows the items according to the active view
You can re-order the layers 
, turn on/off visibility of all objects 
and switch between working modes 
(Fault picks, Horizon picks, Loaded gathers time, Converted gathers time) on current view.
Additionally you can filter vista items by current object type in data manager
