It would be tremendously helpful to be able dump the contents of one bin into another.
A transfer action could be added to the container action list. After selecting “transfer,” a system message would prompt you to then click on another container to select it as the target. Each item in the source container would in turn be either stacked or placed into an empty slot in the target container as appropriate until the target is full.
The system would report one of six results:
transfer failed - insufficient permissions
transfer failed - target full
transfer failed - invalid target
transfer failed - target too far away
partial transfer complete – target now full, items remain in source
full transfer complete
