slider control bounding box/envelope

[AndyQ]

Sorry I'm not sure what the right term for this is, but when using the many slider controls in Photo (especially in the Develop Persona) I'd like to see a wider "bounding box" region around the control for registering a "mouse down? or click. When I'm making adjustments I'm wanting to stare intently at the image itself, not the parameter slider, and I find I have to be too accurate in clicking/holding the positional control when making adjustments. If I lift off for a moment then press again I find I've moved away from the control and it doesn't register my input, so I'm constantly having to shift focus between the image and the control panel. I'm using a wacom so maybe that makes it more difficult, but the sliders are generally spaced far enough apart that the could easily have a much larger "active area" for registering a click/mouse-down without accidental selection of an adjacent slider. I apologise for my poor explanation....I can't think how better to explain it.
