Currently, we have one global slider for both factory & lab spending. Then we have to distribute this money between military, social and research using a three connecting sliders. I find this system a little bit awkward and doesn't allow me to do thing like maximize my research while reducing my industrial spending to meet budget constrain or vice versa. With the current system, I don't know what percentage to set the research slider to optimize for both my research worlds and my industrial worlds.

I would like to see separate spend rate sliders for industrial and research. The industrial spending can split between military and social with another slider.

Advantages:
1. Simpler UI with three sliders instead of the current four.
2. You would have more control over your budget. Why combine industrial & research spending and then reallocate them with three awkward sliders.
