[Orgmode] Looking for some org-mode hooks

[Keith Swartz]

Hi there,

I've recently switched to using org-mode for tracking todo items, and 
I'm finding it to be well worth the effort. I've read through the 
manual, and browsed past messages on the mail archive, but have a few 
questions about whether or not a few enhancements I want to do are 
currently possible in the latest version.

First, is there a hook that gets executed after sorting a subtree? In 
other words, if I'm viewing a subtree as folded/children only, then sort 
it, it changes to display all subtrees. I want it to automatically 
revert back to the visibility I had. I'm hoping I can just set the 
visibility in a hook.

Second, along the same lines, is there a hook that gets executed after 
refiling an item? In this case, I'd like to resort the node to which the 
item has been refiled. So, for instance, if I refile an item with 
priority A to a new node, I'd like that node sorted so that the new item 
appears at or near the top (assuming I sort by priority first).

Thanks in advance,
Keith S.
