Slider simplification and ease

Can they please change the slider settings, or at least give the option, to open up the number pad when selecting a setting that has a slider so you can just type in the number you want instead of holding down a direction for a prolonged time.  Also, for zoom specifications (I.e. 1.00, 1.25, 1.50, etc) give an option to duplicate the same settings for all, or when the number pad comes up it gives recent inputs in the bar above, similar to where possible corrections/predictions exist when typing on a normal keyboard for ease and quickness.  And on a sidenote it doesn't seem that "Zoom Sensitivity Coefficient", which I thought would actually lower sensitivity for all zooms, it doesn't seem to do much at all oddly enough
