The "work asynchronously" option is not being adopted. People want a "simple" way to copy a flighttrack from the operations pane to the "local flight track pane" and back.
In the operation->local direction a simple copy with the same name (and potentially a windows like (1)/(2) tag at the end) would do. In the local->operation direction one/two menu entries with "copy into new operation" "copy into existing operation" would do. The latter would require a dialogue for selecting an operation.
A bigger redesign could allow the selection of track on both sides with arrow buttons or similar, but I prefer the solution described above.
This would allow the removal of the "work asynchronously" button, which allows a very similar feature, but is not being adopted/understood by users on site.
