Lost Tree Resource sort after update a Resource

Hi I see that when you sort the resorce tree with a different criteria than default and then you edit and save a resource, you lost your sort option in the tree and it change to default (I suppose default can be changed).

Is this a bug ? or a feature to implement ?

Version: Modx 2.0.0-pl

A feature to impl; can you file in http://bugs.modxcms.com/ ?

Done
