Problem this feature should fix

• Skybox
• Surface & Point picking
• Solid wireframe

Expected solution

• Skybox

If you want people to utilize your application better, it should have Skybox supported so that user can setup their stage

• Surface & Point picking

You may want to allow users to picking surface / point rather than only object (actor), so that they can modify mesh itself

• Solid wireframe

You may want to consider solid wireframe shading so that user is able to see how their mesh is being rendered and what vertices/surfaces to be modified
