It would be nice to have a search capability to locate ships which are currently using a special component. I often have multiple designs using these components, so have to search each type of ship (let alone if I redesign that).
Reason for this is I want to build an "important" new ship and want that component on it, I have to search entire fleet to find the ship(s) using them (if more than one component) so I can decommission them.
Maybe you could when in designer - mouse over the component which will tell you where it is located.
