Create custom loading screens similar to entity system

[Nolankicks]

For?

S&Box

What can't you do?

Currently, you are unable to modify the loading screen of your game, besides tweaking the text that shows up. I know before the scene system, developers were able to create their own loading screens. Currently what you see is just a very generic loading one.

How would you like it to work?

I would like it to work similar to how it used to work. Or defining a panel to display for the loading screen.

What have you tried?

There is no way currently after the scene system.
