The Suggestions Bar is easy to turn off via Preferences. But I think
Mathematica novices may find it useful, and even experienced users may
find it useful at times, especially when venturing into some new area of
The new built-in (kernel) vector analysis functions should be a boon to
folks needing them.
However, I've always had mixed feelings as Mathematica has grown to
build in more and more mathematical functions. At times this has taken
the edge off what was a valuable exercise for my undergraduate students:
defining more complicated functions -- e.g., div in vector analysis or
nullSpace in linear algebra -- that forced students to understand the
precise underlying definitions and algorithms. And it tended to take
away a sense of power and accomplishment when students could start by
defining the simplest kind of function, such as performing a single
elementary row operation, and step-by-step building ever more
complicated functions, culminating in something relatively
sophisticated, such as finding the orthogonal projection of a vector
upon the span of a given set of vectors, and even going further, such as
using the latter to find the least-squares solution to an overdetermined
