"Swap default click behavior for the Tree menu" - this was an update in 1.01
http://svn.modxcms.com/jira/browse/MODX-929
It works as advertised, but I wonder if it was a good move. With a site that has many managers it gives greater possibility of locked files. Managers may be more enclined to just click a doc to see information on a resource and then close the browser leaving the resource locked. Not a problem with one manager on a site, but when you have 10 or 12 managers it could get tiresome getting a site admin to ’Remove Locks’.
Maybe a system option to set either view or edit as the default click behaviour? In the meantime I located the single line {315 in MODx 1.0.2) in the file manager/frames/tree.php if anyone wants to set it back to view:
parent.main.location.href="index.php?a=3&id=" + id; // edit as default action change a=27 to a=3 for view instead of edit
