 ### Reflection Inspector
 
 * The Reflection Inspector is used for all other supported objects.
 * Allows you to inspect Properties, Fields and basic Methods, as well as set primitive values and evaluate primitive methods.
 * Can search and filter members for the ones you are interested in.

 ### Object Search
 
 * You can search for an `UnityEngine.Object` with the Object Search feature.
 * Filter by name, type, etc.
 * For GameObjects and Transforms you can filter which scene they are found in too.
