Feature Request - Hold shift for smaller sens/increments on sliders and transform

Hi there, I would like to request a feature to hold a key (In Blender the key is L Shift) to reduce the sensitivity of sliders in the details panel (and all other sliders) and also the transform gizmos when dragging with the mouse. This would allow users to more efficiently tweak and fine tune settings in the editor, as currently i find it too sensitive and when i drag with mouse it jumps around too much.

Also i think it would be good to be able to drag up/down or left/right to adjust numeric values such as vector transforms in blueprints and details panel, as well as being able to type a number like the current method.
