Auto collapse open folders in Feeds

I haven't posted anything here in too long, so I thought I should get back into the swing again.  The past few weeks/month have been very busy testing the release candidate here, so you can understand where all of the time goes. 

I wanted to touch base real quick on a new preference that was added that is subtle, but makes a huge difference, at least for me.  This new preference is available in the Reading tab of Feed preferences and it is called, "Collapse open folders when opening a new folder."  When this is checked on, only one folder at a time in the Feeds tab can be expanded.  This is because each time you try to expand a folder other than the one that is currently expanded, the folder that was left behind in an expanded state automatically gets collapsed.  Obviously, this would not occur for a parent folder when expanding a child folder of that parent.

I tend to have a good mix of folders and feeds at the top level and I thought this would be a good pref to add, but I didn't realize how much I was going to like it after it was added in. 
This pref is not available in the collection tab as of yet, but we already have a feature reqest added to the  feature tracking database for adding this at a future release. 

Here is a thumbnail for a  screenshot of the new pref under the Reading tab in Feeds preferences
