Hey Max...
You can use the mouse wheel while hovering over the sliders (most of them, anyway) to make single digit adjustments. I'm planning to re-compile the plugins in the near future. I've made some changes/improvements in the base code over time that the earlier plugins don't have. I'll add some kind of fine control to them when I do that.
Check your messages... I need you to check this thing out. It's not quite ready for publication yet, so if you have any suggestions for it, let me know.
