Whenever I trade techs with an alien, I always check to see if I can get some credits in the bargain. It's handy to use the slider and see when the text turns from green to red, so I know how much I can get. However, the slider is so "sensitive" that it leaps in high increments (hundreds, usually ... I supposed depending upon how much the other trade partner has). For instance, in one instance a mere touch of the slider made it jump from zero to 230 or so, and the only way to get to a number inbetween was clicking the arrows, one credit per click. If it is not possible to have the slider move more slowly, perhaps an "increment button" of 20 or 50 or 100 or something would be nice.
