I've been working on a redesign of the web-based user interface for a
personal health record platform, and I began to wonder -- do I need to
retain the one-line instruction that seems to be on the top of every major
data listing (medications, lab tests, immunizations, etc.):
"Click any item in the list to see more detail" (or something similar
to that effect)
The title of each list item is hyperlinked with underlined, blue text.
I guess the bigger questions are:
Do I assume my users' basic browsing abilities at my own peril?
Does even a basic task of web usage need to be field-tested?
I'm already prepared for the "it depends" answers! ;)
