Right, some are variants and others are characters in their own
right. Practically all of the components are classified to a specific
radical, though.

This type of index is handy from a font development standpoint.
I've tried to set up a database for Plane Two characters from
scratch. It's very time consuming and tedious. (Almost done
through four residual strokes after a considerable amount of
time and effort, and am only counting residual strokes based
on the significant radical.)

Wenlin is a great resource. For me, it's good practice to try
to find a character first, but have been stumped several times and
gone to Wenlin.

An ideal index for the casual or non-CJK user might be quite
different in approach. Perhaps the first component drawn in
any character would be a good basis for indexing rather than
the significant radical. But, as you've pointed out, not all
components are immediately recognizable as pertaining to a
particular radical, especially to the casual user.
Since the Han Radical Index in the Unicode book functions the
same as a radical index in a Chinese dictionary, I balked at the
idea of having any character appearing under a non-significant
radical, at first. But after more thought, I don't suppose any
laws would be violated if characters appeared in more than one
location. It sure would make look-ups easier. Meanwhile, I'll
take your advice and keep an eye on Wenlin.
