I have a UserControl that acts as a container for a number of other controls on a Form.  Because any of these controls can have a DockStyle of Fill, this makes selecting the containing UserControl in the designer a tedious action for a developer.  Selecting the control is a necessity because a lot of design-time functionality has been built into smart tags (designer actions).  If the developer can't easily select the control on the form, he/she can't easily access the smart tag either.

To solve this, I'd like to be able to force my control to not only appear on the Form as usual, but to also appear in the Form designer's Component Tray.  An icon in the component tray would make it very easy for a developer to quickly select the control and access the smart tag.

How would I go about implementing this?
