AutoCAD Inventor :: IFeature Folder Paths

I'm a single user at a small company tooling company.  I've created a handful of useful iFeatures that I've saved just in the default path:  C:UsersPublicDocumentsAutodeskInventor 2013Catalog

However, we're in discussions now about hiring another designer, so as I do new projects, I've been trying to do things cleaner and making sure that the method to my madness is obvious.  So I'm considering moving the contents of this folder to a network drive, and also one that's independent of Inventor upgrades (version # in the folder path). 

My question is this:  In the application settings, there are (3) different path settings on the iFeatures tab.  How are these different? 

When I've developed iFeatures I've usually had them initially in the Workspace directory for the current project.  Once completed and tested, I would put them in the default folder.  When I go to insert one later, the "Insert iFeature" dialog box doesn't take me to this path and I have to look it up all the time.  It just takes me back to wherever I inserted the last one from.  So what does this path in the settings box actually do for me?

If there's no "shortcut" to point to the iFeature root folder quickly, why do I care where I put them?  Couln't I create a network folder such as "Z:CADifeatures" for these and add it as a Library to my projects and save myself time?  I'd also not have to change the settings and/or make copies when we upgrade to IV2014.

Would there be a downside to doing this?  It almost seems too easy and like there's room for product improvement here.
