Has nothing to do with “senior”... simply with the demand that everyone on every platform they are interested in using be able to present items they are served in every possible configuration. CSS demands create more malware opportunities than anything else does.
I have been happy with the ancient presentation of FR that was used 20+ years ago. Happily, it has remained pretty much the same. I never noticed the “brevity” switch, and somewhere along the line it nabbed me, and trying to look at my profile switches provided no clues.
In any event, the problem’s done now, thanks to the good folks who answered me above.
