Use this package to apply a custom sort order to nodes. You can configure which docTypes will be sorted. Once a document of a specified type is published or created, all sibling nodes will be sorted.
You're able to specify in configuration whether or not to republish nodes after applying the sort, so this can be used for a back-end-only utility (fast) or for both back and front-end sorting (slower). The former will still perform well on nodes that have a large number of children; the latter will not perform as well in that case.
Currently supports (see /config/nodeSorter.config):
Sort alphabetically ascending/descending
Sort by date created ascending/descending
At this point, this should be considered RC code. It has proved to be stable in our testing environments, but that may not be the case for EVERY environment. We are looking to collect feedback.
Tested on Umbraco 4.7.
