Quickly find objects and navigate your map using Placed Objects
You can find the 'Placed Objects' button at the top of the left menu bar
Clicking into this will show you a condensed breakdown of every item placed on your map. These are grouped into folders based on their category. Clicking into one will show you all the objects in that folder.
Clicking the name of one of these objects will move your map to wherever that object is placed, and open the objects' properties panel. Clicking the eye button, next to the object name will hide this object in the map view.
You can also use the Placed Objects menu to hide and unhide the labels for entire folders of objects, and objects individually.
