Imagine the default toolbox collapsed and only user defined folders/toolboxes to be displayed. What a difference!
When adding toolboxes, the user's toolbox is intermingled with Default toolboxes. Just adds confusion and frustration when trying to locate my toolboxes within the default toolboxes.
Some type of folder structure would help, one larger than the toolboxes, such that toolboxes can be orgainized. Allowing these to collapse would be helpful as well.
At a minimum, the default toolboxes should be separate from the user toolboxes. While I don't want to get rid of the default toolboxes (need quick access for development/reference), I would like to not show them while seeing my custom toolboxes.
