Inspector
The Inspector displays properties for the currently selected object. You can lock the current selection to the inspector by toggling the lock icon.
Entities
If you are using the built-in entity scenes module, you can add, edit and remove components to objects selected from your scene.
Click the Add Component button at the bottom of the components list to add a new component. Right click any components header and select "Remove" to remove the component from the objects entity. The Transfrom component cannot be removed.
Refer to Components for more information about the built-in components.
If an entity object is selected, you can edit its name in the Name field, or inspect its ID underneath the Name field.
Custom editors can be made via editor extensions, these expand the inspector to support any object you may need.
