Did you try e.g. complex_plot(x-abs(x), (-1,1), (-1,1))
The plot contains more information than just the region of zeroes. Usually the phase information is quite interesting. I don't think we have a function to just give you the zeroes (which is numerically difficult)

How do you plot the zeros of a complex function in sage? For instance, I am interested in plotting the zero sets of some complex functions with a continuous family of zeros (i.e. f(z)=z-|z|), in a way that is independent of how complicated the expression for f(z) is.
