UI: Make "Controls" section only show objects from selected Scene

[folknor]

Hi,

It might be an idea to change the UI so that the "Controls" section only shows controls for the currently selected Scene.

Especially when a project becomes serious and has like 5 different scenes with tons of images and text, there is a lot of stuff going on in Controls that is not relevant to what I'm currently editing.

Thanks for reading, and thank you for the excellent application!

That would be a good feature to add.
