I can empathize with you. While I do not have a medical condition as you, age has caused my hands to be very shaky. It is frustrating doing fine work. Must always have my hands firmly resting on a heavy object to get any small work done.
Hopefully one of the forum members can help you. The problem for most people, including me, is lack of time. Shucks, I can't seem to find any real time to spend on my layout and I have quite a queue of my own RP installs.
