Details Panel

The details panel displays information about what you've selected

In this image, the example shows I've selected the UEditor logo, it displays it's name inside the text box

The TextBox is disabled, as you cannot change the Actors name in realtime.

In the details panel, you can also see sections like Transform, Settings, Physics and more. They are all very self explanatory.

Adding Components

The menu will get a list of components and put them into this dropdown, you can attach components to Actors. For example a Interaction component would be fun, as it could allow you to pick up things that aren't supposed to be picked up.
