Removed tne unused "keywords" field from the DB, adjusted setup.php to suit. This was an idea for an extra field, not displayed, containing search content, but won't be used.
In map.js, the popup bubbles now call the list of categories "Tags:" instead of "Categories:"   This is more generic than Categories or Amenities.
* Admin & Site: complemented administration.js (sitewide JavaScript within the admin panel) with site.js (sitewide JavaScript on the front-facing site)

* added to administration.js and site.js a jQuery ajaxSetup() which disables caching of GET requests

* Map page: nicer layout and consistent resizing of right-hand side
Enabled the "Search by keyword" section of the Map page. This searches categories, place names, and place descriptions.
Improved the handling of tabsets (jQuery UI Tabs widget) in the admin panels:

* on page load the URL is checked for a hash component,  and if found then this tab is selected. This allows one to link directly to a tab.

* when changing tabs, the URL is updated in the address bar, to have that has; this allows document.location.reload() to work properly, refreshing the page and also selecting the hash/tab

In the admin panel for Place Data Sources, and in the administration.php controller when one is redirected to the Place Data Sources page, hash components have been added to make navigation just a little simpler and smoother.
Place Data Source, ArcGIS REST driver: Description field is now optional; one may specify that there is no description field, which means blank descriptions.
