Perhaps this is a Bug, but it would be much more intuitive if ORD Explorer would automatically update while docked (specifically the "OpenRoads Model" portion). As it is right now, you constantly have to close explorer and re-open it to see updates which is not very intuitive at all and causes unnecessary confusion and frustrations.

EDIT: Explorer does update the actual features (add, delete, rename etc), but if you delete something, the feature definition entry still remains (even if that specific feature definition is not used anywhere in the file) Refreshing explorer does not remove it/clean up the list. You need to close explorer and re-open it. However, the more I look at this, it doesn't seem like as big of a deal as some users have reported, but I do think that hitting "Refresh" should clean up the list removing any unused Feature Definitions)
