                 <li>The display of history data has been postponed until a future release.
                 <li>Some additional categories of source specific concept data are not included, but are being considered for inclusion in future releases.
               </ul>
  -            <li><b>Functionality</b>: Performance has greatly improved and remaining problems have been partly designed
  -            around, but there are still issues with extensive relationship and hierarchy data that we intend to fix.
  -            User-settable options and the ability to search other concept data and relationships are needed, and should
  -            be part of forthcoming browser releases.
  +            <li><b>Functionality</b>: Performance has greatly improved, but has been partly offset by the several-fold increase in
  +            data.  Search results are ranked by goodness of match, but Contains searches had to be limited to the beginning or
  +            end of words to get good performance. There are still performance issues with the display of concepts having many
  +            thousands of relationships, and hierarchy display is still painfully slow. User-settable options and the ability to
  +            search other concept data and relationships are needed, and should be part of forthcoming browser releases.
               <li><b>Documentation</b>: Online and standalone documentation are still under development.

                or in other ways.
                <li><b>Synonym Details</b>: For each term or abbreviation, shows its source, term type, and code.
                <li><b>By Source:</b> Shows concept information one source at a time. NCI Thesaurus content is shown
                if available, otherwise the initial source is chosen alphabetically. To view concept information from
