OK, I'll go first. As a VW newbie, I found the fonts too small (even when I specified 'large' on the settings page) and the default grey background (on Solaris, which uses the Motif Look Policy) made it even harder to read the stuff I was typing. After many frustrating hours, I managed to change the background color and I finally found out how to change the preferred font pixel size. My point is that all of this is much too hard for someone completely new to VW. There should be a dialog box to change fonts and/or font sizes with lists of available fonts that I can pick from. There should also be a box like the one found in Windows98 Display Properties -> Appearance for setting colors.

Complex numbers caused me considerable grief for some days.
One bad thing about them is that Complex class>>real:imaginary: does not necessarily create a complex number, depending on the imaginary part. As a consequence, as soon as you perform inner product operations with vectors, you can't simply write
a * b conjugated,
but have to use
a * b asComplex conjugated.
As a result, my program spent 60% of its time generating superfluous temporary complex numbers.
I got this fixed by adding methods real, imaginary, and conjugated to ArithmeticValue. They just return self, 0, and self.
This seems to be a rather critical fix for scientific computing, but making complex numbers fully functional in a mathematical context will probably require a fair bit of redesign.
