Responding to the last several posts:
1) The column heading can be whatever you want.
2) The lookup name must be lower case. You prefix this name with a '#' to use the column. In your case, #genre.
3) I agree, the history can get annoying. I will look at fixing this by making the completion case sensitive. In this case, work around it by putting an extra space before the first slash. Calibre will remove that extra space later. Your assumption is correct: the plugin value takes precedence over the general one.
