Personally I find that trying to set constrants to be very tiring, especially on the eyes. Trying to get the mouse cursor located on a node where you get the cross hair to turn on is very tiring. I can put the mouse cursor right on top of a node and I have to wiggle it all over to get the cross hair to turn on. And the margin of error is so small that it can get quite frustrating at times. I especially find trying to get the cross hair when finding the center of a circle to be THE most tiring of all.

I'm wondering if there is anything, from a programming point of view, to make this less tiring?
I'm hoping other users will put their findings here so we can present some useful information to Thermwood. This is NOT meant to be a bashing session. It is meant to gather some useful information for Thermwood. So if you feel so inclined to bash a feature, please try to reword it to be non-bashing or don't post it.
Thanks!!
