Revised implementation of Category Tree,s includes:
1) Ability to optionally turn off the display of the Cat Tree status window, which in many cases takes up too much screen real estate with no appreciable value.
2) Ability to optionally have Cat Tree display open by default
3) Cat Tree operations now are more intuitive. When the tree first opens, any branch that has a checked item will be expanded automatically. Selecting a child branch will automatically select all parents. Deseleting a child will NOT deselect parents any more (I considered that a bug).
4) Searches using CatTrees can now be set to use "AND" logic rather than "OR" logic (optionally). In the past (and by default) if you searched for something like: animal;tiger;siberian;kazan by selecting Kazan in a CatTree, the search would return all images that had the keyword animal, which is typically not what you want. You want only resources that match all selected levels in the Cat Tree hierarchy, that is where a resource has keyword "animal" AND "tiger" AND "siberian" AND "kazan". Not OR as was/is the default.
5) Default behaviour (except for selection fixes per item 3 above) remain as it was. Optional behaviour can be enabled in your config.php file.
Plus a couple of bonus features:
1) favicon is now set for ResourceSpace pages, so that browsers show the grey cube on shortcuts.
2) Contact sheet image preview size can now be specified in config.php as follows:
$contact_sheet_preview_size="400x400";
Default remains at the previous 250x250 size in config.default.php
