The current method for removing ghost images is not intuitive and not very helpful.
Those who want to retain the image must figure out that they need to restock an SDB before removing currants -- and even once learned, this is inconvenient and easy to forget.
Those who want to use ghost images for decorating purposes are SOL. This is sad for me, as I found this hugely fun before it was no longer possible. (Please, please don't take away the ghosts that were created before the change!)
Those who want to remove a ghost image must put something for sale in the SDB and then get someone else to buy it so that they can then remove the currants.
A menu option would be easy to discover and understand, while allowing the ghost image to be retained by those who want it. This would be helpful for organizing, restocking and decorating. It also might lead to a fun market in SDBs with ghost images.
