I think it needs to be remembered that this is art as well as craft...
For the most part I've had to turn off smart grid and any tools like it (auto zoom is one for me)...
Trying to guess my circumstantial needs is beyond my own ability even if we could set such...
That being said, I use mostly the same snap settings... One setting for TV and another for PRV... It is awkward to work on some pieces/situations where I must change back and forth to different settings such as in PRV needs for some phrases that require triplets or the likes, but that is infrequent for me...
So it's simple for me to simply disable it and ignore it with a sigh thinking all that features development time could have gone into redesigning Lanes and Zoom! <sigh>...
