//An interface for when we can’t user manipulators.//
For some tools, we require input for things that don't map well to a spatial 3D manipulator widget. For this reason, we want to add a numerical manipulator widget to adjust the current tool.
It appears when using a tool, after you've created the initial action - after your Extrusion, your Spin, your Bevel action etc.
This will be implemented via the manipulator system.
//Below are some examples of where this is applicable://
Add Cylinder tool:
Add Sphere tool:
We //could// even add it for some commands, such as Subdivide:
We want this interface to be as unobtrusive as possible, while still being easily accessible.
Rather than re-using the large F6 panel, we wanted to make something that will stay out of the way, yet appear close the manipulators when needed.
We've ended up with this thin 'bar' approach, which sits near the bottom of the 3D View.
