>>Hi Dan,

>>>When adding a property, it brings up a small form. Here you have the choice to add one item, the color picker, a getfile() or a drop down list. You can also add items to a drop down list which would allow you to cycle by double clicking or pull up the drop down list. The list would have a place for descriptions along side your choices.

Reserved fields in the VCX should be a good place. The names of custom properties and methods, along with comments, are stored there. Few extra data wouldn't hurt.
