I have a small problem. Integrating the diff command works well up to the 3rd derivative <meaning diff(y(x),x,3)>
I actually use this. Fixable?

Re: integrating the diff command
This comes from the fact that intermediate derivatives are added to the list of depending variables of the expression, and there is a maximum value for checking f(u)*u' forms. The max value could be increased, but it would still fail for a larger derivative number. I don't think it's worth it, unless you have some real life example where it would help (I mean do some real computation that you can not do yourself).
