The Object Lister now enables you to:
The layer labels displayed in the Object Lister are now identical to the layer names (or layer numbers) appearing in the Layer Bar.
Show > By Objects shows objects in more useful order
When Show is set to By Object, the objects are now ordered as follows:
This special arrangement gives you the ability to further arrange, group, and order objects.

Right Click with Show > By Object
Dynamically rearrange objects by selecting one or more objects (using Ctrl or Shift keys) and right-clicking while in Show > By Object mode. A menu opens with the following items:
Makes picked objects visible or invisible. When visible objects are picked, right-clicking shows the check mark turned on. When turning the check mark off, these objects become invisible in the view window, and are grayed out in the Object Lister.
Previously, you could only make one object or group invisible at a time.
Creates a new group node and places the picked objects inside.
This choice becomes active only when right-clicking on a Group Node. It places the picked objects into this Group Node
Right-clicking on any object and selecting one of these options places the already picked object(s) before or after the specific object.
These two choices are only active when it is possible to insert into the current position. For example, they are grayed out when geometry is picked if you right-click on a Group Node surrounded by other Group Nodes (since geometry cannot be inserted between Group Nodes).
This button works as "Expand All" or "Collapse All" for all Group Nodes and envelopes.
Click on +/- All and all Group Nodes and envelopes are collapsed. To expand them, click +/- All again.
Enhances the workflow of dynamically sorting and arranging objects.
For example, if you have a large model, type “Rail” in this field, then press the Enter key. All objects whose names start with “Rail” (case insensitive) are picked in the Object Lister, as well as the modeling window. You can scroll up and down in the Object Lister to check the picked objects and can cross-check in the modeling window.

Hold the Ctrl key and click to unpick the rail objects that are not required for the group. Then create a new Group Node or put the rail objects in an existing Group Node.
If a collapsed Group Node has a picked Rail object, the Group Node expands, to make it easier to find the picked geometry.
You can also use the “*” character as a wildcard. For example, *shell* will find all objects whose names contain the string “shell”, and *30 will find all objects whose names end with “30”.
If certain objects are picked and are not visible in the Object Lister, click the scroll up button to reach to the lowest picked object and show it at the top of the Object Lister window.
Clicking once more on the button will show the next picked object, and so on.
Finds the highest picked object and shows it at the bottom of the Object Lister window. Click the button again to reach the next picked object.
