Good changes, but now I realized I can get out without ever using the sphere by just moving the box once I get to the sphere area. If you change the flip-plate so you need it to get to the sphere receptical, attach it to the second cube receptical, and make the Sphere unlock the Exit, Everything would be required. Probably other ways to do it.

Okay, I think I know what you mean. Thanks for playing my test!

I got to the sphere before the cube with a bit of a tricky jump. You may want to make the squares on the floor around the lift non-portalable. I put a portal next to the ramp and steped onto it instead of jumping as well.
