I implemented zooming in Field (which is what I renamed Workings
to). For some reason, I thought it'd cause all sorts of problems, like conflicts with dragging, but it went pretty smoothly. It does occasionally lock up, and I should turn off the physics stuff when zooming is happening.

(And yeah, I need to declutter that UI. Property sheets, begone!)
The full name is Personal Forces Field because it's a field where you personally define a bunch of your forces. I'm not super sure about that name, either, but it is a step up from Workings. I was also considering Forces Sources, which amuses me greatly, but is awkward to say.
