This may have been discussed, or there may be a setting I am unaware of....

But it drives me nuts to look at the Keyword panel, and see them listed alphabetically. I want to review the keywords I've assigned, in the hierarchy that they are organized in, probably in multiple lines for each Parent keyword....this would be a much more comprehensible way of viewing the keywords I've attached to a photograph.

This sounds like a reasonable request for a feature in version 3 of Lightroom.
